\section{Introduction}

Over the past decade or so, a number of observations have been interpreted as possible signals of annihilating or decaying dark matter particles. Examples of such observations include the 511 keV emission from the Galactic Bulge~\cite{Boehm:2003bt}, an excess of synchrotron emission known as the WMAP Haze~\cite{Finkbeiner:2004us,Hooper:2007kb}, an excess of high energy positrons in the cosmic ray spectrum~\cite{Adriani:2008zr,Aguilar:2013qda}, a mono-energetic line of 130 GeV gamma rays from the Galactic Halo~\cite{Weniger:2012tx}, and a 3.5 keV X-ray line from Perseus and other galaxy clusters~\cite{Bulbul:2014sua,Boyarsky:2014jta}. Each of these anomalies, however, has either failed to be confirmed by subsequent measurements~\cite{Ackermann:2013uma,Aharonian:2016gzq}, or has been shown to be quite plausibly explained by astrophysical phenomena~\cite{Hooper:2008kg,Cholis:2013psa,Crocker:2016zzt,Su:2010qj}.

In comparison to these other anomalous signals, the gamma-ray excess observed from the Galactic Center by the Fermi Gamma-Ray Space Telescope stands out. This signal has been studied in detail over the past seven years~\cite{TheFermi-LAT:2015kwa,Daylan:2014rsa,Calore:2014xka,Hooper:2013rwa,Gordon:2013vta,Abazajian:2012pn,Hooper:2011ti,Hooper:2010mq,Goodenough:2009gk,Zhou:2014lva,Huang:2015rlu} and has been shown with high statistical significance to exhibit a spectrum, morphology and overall intensity that is compatible with that predicted from annihilating dark matter particles in the form of a $\sim$\,30-70 GeV thermal relic distributed with a profile similar to that favored by numerical simulations. Although astrophysical interpretations of this signal have been proposed (consisting of either a large population of millisecond pulsars~\cite{Cholis:2014lta,Lee:2015fea,Bartels:2015aea,Petrovic:2014xra,Hooper:2013nhl,Hooper:2015jlu,Hooper:2016rap,Brandt:2015ula}, or a series of recent leptonic cosmic-ray outbursts~\cite{Cholis:2015dea,Petrovic:2014uda,Carlson:2014cwa}), these explanations require either a significant degree of tuning in their parameters~\cite{Cholis:2015dea}, or pulsar populations which are very different from those observed in the environments of globular clusters or in the field of the Milky Way~\cite{Hooper:2016rap,Hooper:2015jlu,Cholis:2014lta}. In addition, some modest support for a dark matter interpretation of this signal has recently appeared in the form of excesses in the cosmic-ray antiproton spectrum~\cite{Cuoco:2016eej,Cui:2016ppb,Hooper:2014ysa}, in the gamma-ray emission from the dwarf spheroidal galaxies Reticulum II and Tucana III~\cite{Geringer-Sameth:2015lua,Drlica-Wagner:2015xua,Hooper:2015ula,Li:2015kag,Fermi-LAT:2016uux}, and from the observation of spatially extended gamma-ray emission from two dark matter subhalo candidates~\cite{Bertoni:2016hoh,Bertoni:2015mla,Xia:2016uog,Wang:2016xjx}. At this point in time, however, there is no clear resolution to the question of the origin of the Galactic Center excess.

\caption{A summary of the simplified models identified in Ref.~\cite{Berlin:2014tja} as being potentially capable of generating the observed characteristics of the Galactic Center gamma-ray excess without violating collider or direct detection constraints (as of June 2014). For each model, we list the nature of the dark matter candidate and the mediator, as well as the form of the mediator's interactions. In the final column, we list whether the leading elastic scattering cross section with nuclei is spin-independent (SI) or spin-dependent (SD) and whether it is suppressed by powers of momentum, $q$, or by loops.}
\end{table*}%

Many groups have studied dark matter models that are capable of generating the observed features of the Galactic Center excess (for an incomplete list, see Refs.~\cite{Ipek:2014gua,Boehm:2014hva, Hooper:2014fda,Berlin:2014pya,Agrawal:2014una,Berlin:2014tja,Izaguirre:2014vva,Cheung:2014lqa,Cerdeno:2014cda,Alves:2014yha,Hooper:2012cw,Ko:2014gha,Boehm:2014bia,Abdullah:2014lla,Martin:2014sxa,Cline:2014dwa,Kim:2016csm,Karwin:2016tsw,Ghorbani:2014qpa}). In this study, we follow an approach similar to that taken in Ref.~\cite{Berlin:2014tja}, and consider an exhaustive list of simplified models that are capable of generating the observed gamma-ray excess while remaining consistent with all constraints from collider and direct detection experiments. Also following Ref.~\cite{Berlin:2014tja}, we choose to not consider hidden sector models in this study, in which the dark matter annihilates to unstable particles which reside in the hidden sector, without sizable couplings to the Standard Model (SM)~\cite{Abdullah:2014lla,Martin:2014sxa,Hooper:2012cw}. While such scenarios certainly remain viable, we consider them to be beyond the scope of this work.

The models found in Ref.~\cite{Berlin:2014tja} to be compatible with existing constraints from direct detection and collider experiments are listed in Table~\ref{table1}, and can be divided into three categories. First, there are models in which the dark matter annihilates into SM quarks through the $s$-channel exchange of a spin-zero mediator with pseudoscalar couplings. These models allow for an unsuppressed ($s$-wave) low-velocity annihilation cross section while generating a cross section for elastic scattering with nuclei that is suppressed by either two or four powers of momentum, thus evading direct detection constraints. In the second class of models, the dark matter annihilates through the $s$-channel exchange of a vector boson. In this case, it was found that direct detection constraints could be evaded if the mediator couples axially with quarks or couples only to the third generation. Lastly, there are models in which the dark matter annihilates to $b$-quarks through the $t$-channel exchange of a colored and electrically charged mediator.

In this paper, we revisit this collection of dark matter models, applying updated constraints from the Large Hadron Collider (LHC) and other collider experiments, in addition to recent constraints from the direct detection experiments LUX~\cite{Akerib:2016vxi} and PandaX-II~\cite{Tan:2016zwf}. We find that many of the models previously considered within the context of the Galactic Center excess are now excluded by a combination of these constraints.

\section{Constraints}

In this section, we summarize the constraints that we apply in this study. In particular, we consider constraints from the LHC and other accelerators, as derived from searches for mono-X events with missing energy (where X denotes a jet, photon, or $Z$), di-jet resonances, di-lepton resonances, exotic Higgs decays, sbottom searches, and exotic upsilon decays~\cite{Khachatryan:2016zqb, Khachatryan:2015dcf, CMS:2016pod,CMS-PAS-SUS-16-016,ATLAS:2016cyf,Aaboud:2016tnv,Aaboud:2016uro,CMS-PAS-HIG-16-006,CMS-PAS-HIG-16-025,Barate:2003sz,Dolan:2014ska}. We also summarize the current status of direct searches for dark matter, including the recent constraints presented by the LUX~\cite{Akerib:2016vxi} and PandaX-II~\cite{Tan:2016zwf} Collaborations.

\subsection{LHC}
\label{LHC}

Searches at CMS and ATLAS provide some of the most stringent constraints on dark matter, as well as on the particles that mediate the interactions of dark matter. In this study, we consider the bounds from the LHC as applied to a wide range of simplified models, the most stringent of which arise from CMS searches for mono-jet+MET, di-jet resonances, di-lepton resonances, di-tau resonances, and sbottom searches. Although we also considered constraints from the ATLAS Collaboration, they were slightly less restrictive than those from CMS.

LHC limits are typically published in one of two ways: (1) assuming a particular model and choice of couplings, a limit is presented on the parameter space in the dark matter mass-mediator mass plane, or (2) a limit is presented on the product of the production cross section and the branching fraction for a particular process. In this study, we will present our results in terms of the mediator mass and the product of the dark matter-mediator and SM-mediator couplings. Thus applying limits from the LHC generally requires translating these bounds into the parameter space under consideration. To calculate the relevant production cross sections and branching ratios, models are built using FeynRules~\cite{Alloul:2013bka} and subsequently imported into MadGraph5\_aMC@NLO~\cite{Alwall:2014hca, Hirschi:2015iia}. When necessary, we implement PYTHIA 8~\cite{Sjostrand:2007gs} to hadronize the final state particles and DELPHES~\cite{deFavereau:2013fsa} to simulate the detector response. As appropriate, we apply the published cuts on MET, final state momentum, and final state rapidity in our calculations. Throughout this study, we calculate and present all LHC constraints at the 95\% confidence level.

In scenarios with heavy mediators, it is not uncommon for the width of the mediator to be unacceptably large (i.e.~ as large or larger than its mass). Such widths are clearly not physical and may indicate the presence of additional particles or interactions~\cite{Duerr:2016tmh,Englert:2016joy,Boveia:2016mrp,Kahlhoefer:2015bea,Abdallah:2015ter}. Imposing unitarity and gauge invariance often restricts the mass of such additional particles to be of the same order of magnitude as the other dark sector particles, making it difficult to define the properties of these new particles such that they are beyond the reach of the LHC. Although the construction of more complicated dark sectors is beyond the scope of the work, we emphasize that it is likely that constraints derived on such models would be more restrictive than those derived here. Throughout this study, in order to maintain the validity of the theory in this region of parameter space, we apply LHC constraints assuming $\Gamma/m = 0.1$ whenever the width of the mediator would otherwise exceed this value.

\subsection{LEP-II}

Constraints from LEP-II on Higgs bosons in the mass range between $10$ GeV and $100$ GeV are extremely constraining for a wide range of beyond the SM physics scenarios. In this study we consider such limits as derived from searches for a light Higgs decaying to $b\bar{b}$~\cite{Barate:2003sz}. Although powerful, these constraints are rather model dependent, and generally rely on the scalar mediator's coupling to the SM gauge bosons. LEP-II constraints are presented at the 95\% confidence level throughout this work, and assume a coupling to the Z-boson identical to that of the SM Higgs.

\subsection{BaBar}

We also consider in this study constraints derived from BaBar on upsilon decays to light scalar or pseudoscalar particles, in particular focusing on channels where the mediator subsequently decays to hadrons, muons, taus or charm quarks~\cite{Lees:2011wb,Lees:2012te,Lees:2012iw,Lees:2015jwa}. We consider relativistic and QCD corrections for the decay of a vector meson as described in Ref.~\cite{Dolan:2014ska}. We note that the $\mu^+ \mu^-$ channel provides the strongest constraints, but the precise values of the branching ratios of such light scalars are not well known (see e.g.~Refs.~\cite{Dolan:2014ska,Clarke:2013aya}). Here, we conservatively assume a 100\% branching ratio to hadrons in the mass range of $1 \, {\rm GeV} \lesssim m_{A} \lesssim 2 m_\tau$. This is conservative in the sense that introducing a small branching ratio to muons strengthens the resulting bound. For $ 2 m_\tau \lesssim m_{A} < 9 \, {\rm GeV}$, we use the branching ratios as recently computed in Ref.~\cite{Haisch:2016hzu} which incorporate QCD corrections. We find similar constraints as those previously obtained in the recent analysis of Refs.~\cite{Dolan:2014ska} and \cite{Clarke:2013aya} for pseudoscalar and scalar mediators, respectively. All BaBar constraints are presented at the 90\% confidence level in this study.

\subsection{Direct Detection}

The constraints utilized in this study on the dark matter's elastic scattering cross section with nuclei have been derived from the latest results of the LUX Collaboration~\cite{Akerib:2016vxi}, which are only slightly more stringent than those recently presented by the PANDA-X experiment~\cite{Tan:2016zwf}.

For all tree-level cross sections, we use the expressions as presented in Appendices B and C of Ref.~\cite{Berlin:2014tja}. One-loop cross sections for the scalar mediated $t$-channel interaction and the $s$-channel vector mediated loop-suppressed interaction are provided in Refs.~\cite{Agrawal:2014una} and~\cite{Kopp:2009et}, respectively. The remaining $t$-channel models, which are also loop suppressed, suffer from the problem that they are not generically gauge invariant. Consequently, scattering cross sections for these models are calculated by introducing a factor that suppresses the cross section by the same factor that would appear if the interaction were mediated by a massive photon, i.e.~ $\left(g^2 \log(m_b^2/m_{\rm med}^2) /(64\pi^2m_{\rm med}^2)\right)^2$.

For each model, we calculate the expected number of events in a xenon target following the procedure outlined in Ref.~\cite{Savage:2008er}, adopting a standard Maxwellian velocity distribution ($v_0 = 220$ km/s, $v_{\rm esc} = 544$ km/s, $\bar{v}_{\rm Earth}=245$ km/s), a local density of $0.3 \, {\rm GeV/cm^3}$ and an exposure of $3.35\times 10^{4}$ kg-day. Form factors and nuclear responses are calculated following the procedures outlined in Refs.~\cite{Cheng:2012qr,Fitzpatrick:2012ix}. We take the efficiency for nuclear recoils as a function of energy from Fig.~2 of Ref.~\cite{Akerib:2016vxi}, and derive bounds at the 90\% confidence level, assuming $4.2$ expected background events and applying Poisson statistics.

\section{Pseudoscalar Mediated Dark Matter}\label{spin0med}

In this section, we will consider models in which the dark matter annihilates through the $s$-channel exchange of a spin-0 mediator, $A$. We begin by considering a fermionic dark matter candidate, $\chi$, with interactions as described by the following Lagrangian:
\begin{equation}
\Lag \supset \left[ a\bar{\chi} \lambda_{\chi p}i \gamma^{5} \chi + \sum_{f} y_{f}\bar{f}(\lambda_{f s} + \lambda_{f p}i \gamma^{5})f \right] A \, ,
\end{equation}
where $a = 1 (1/2)$ for a Dirac (Majorana) dark matter candidate. Although we describe the interactions of the SM fermions in terms of their yukawas, $y_f \equiv \sqrt{2} m_f / v$, the quantities $\lambda_{fs}$ and $\lambda_{fp}$ allow for arbitrary values of each coupling. Here, $v$ is the SM Higgs vacuum expectation value, i.e.~ $v \simeq 246$ GeV. Assuming that $\lambda_{bs}$ or $\lambda_{bp}$ is not much smaller than that of the other SM fermions, dark matter will annihilate largely to $b\bar{b}$ in this model. For this dominant annihilation channel, a dark matter mass of approximately 50 GeV is required to generate the observed spectral shape of the Galactic Center excess~\cite{Calore:2014xka,Calore:2014nla}, and we adopt this value throughout this section.

The black dashed (solid) lines include (neglect) annihilations to mediator pairs for several values of $\lambda_r \equiv \lambda_{\chi}/\lambda_{b}$. The upper boundary of the shaded black region is where the correct thermal relic abundance is obtained, whereas along the lower boundary the low-velocity annihilation cross section is at its minimum value required to potentially generate the observed gamma-ray excess. The constraints from CMS assume $\lambda_r = 1/3$ (solid) and $\lambda_r = 3$ (dash-dot), and are compared with the bounds enforcing $\Gamma_A / m_A = 0.1$ (purple) for the same coupling ratios. LEP and BaBar constraints are presented for $\lambda_r = 10$ and 1, respectively.}

\caption{\label{fig:spin0med_ps_s_tbeta} As in \Fig{fig:spin0med_ps_s} but for $\tan \beta = 10$, where $\tan \beta$ is defined as the ratio of the mediator's couplings to down-type and up-type fermions.}
\end{figure*}

In the left (right) frame of Fig.~\ref{fig:spin0med_ps_s}, we plot the constraints on the parameter space of a simplified model with dark matter in the form of a Dirac (Majorana) fermion and a mediator with a pseudoscalar coupling to the dark matter ($\bar{\chi} \gamma^5 \chi$) and scalar couplings to SM fermions ($\bar{f}f$), assuming a common scalar coupling to all SM fermions (as motivated by minimal flavor violation), $\lambda_{fs}$\footnote{Note that the product of couplings in these models be quite large, occasionally appearing to violate perturbativity. This need not be the case, however, as we have not included the yukawa contribution to the SM coupling, which may significantly suppress this product.}. In each frame, the upper boundary of the shaded black region represents the the value of the product of the couplings that is required to generate an acceptable thermal relic abundance, assuming standard cosmology. The lower boundary of this region corresponds to a more relaxed assumption, requiring only that the low-velocity annihilation cross section is large enough to potentially generate the observed gamma-ray excess, $\langle \sigma_{_{\chi \chi}} v \rangle > 3 \times 10^{-27}$ cm$^3/$s (or twice this value in the case of a Dirac particle). If $m_A < m_\chi$, dark matter can annihilate directly to mediator pairs via t-channel $\chi$ exchange. In these figures, we plot as dashed black lines the parameter space which generates the observed thermal relic abundance for several values of $\lambda_r \equiv \lambda_{\chi}/ \lambda_{b}$. One should keep in mind that if the dark matter annihilates significantly to mediator pairs in the low-velocity limit, a higher value for the dark matter mass is generally required in order for the resulting gamma-ray spectrum to be consistent with the observed features of the Galactic Center excess~\cite{Berlin:2014pya,Abdullah:2014lla,Martin:2014sxa}. We compare these curves to the constraints derived from LUX (blue), CMS/LHC (red), LEP (green), and BaBar (yellow).

In the case of CMS, the most stringent constraint in this class of models derives from searches for events with a single jet and missing transverse energy (MET).  As the sensitivity of collider searches depends not only on the product of the couplings, but also on their ratio, we present constraints for multiple values of $\lambda_r$. In Fig.~\ref{fig:spin0med_ps_s}, the solid (dot-dashed) lines correspond to CMS constraints for $\lambda_r= 1/3$ $(3)$, while LEP and BaBar constraints are derived assuming $\lambda_r = 10$ and $\lambda_r = 1$, respectively. The regions bounded by a purple solid (dot-dashed) line represent those in which the calculated width of the mediator exceeds one tenth of its mass, for $\lambda_r= 1/3$ $(3)$. As described in Sec.~\ref{LHC}, we set $\Gamma_A = 0.1 \,m_A$ throughout this region of parameter space, and take this to be indicative of additional particles and/or interactions that are not described by our simplified model.

The constraints from LEP rely on an effective coupling of the SM $Z$ to $ZA$, and are thus highly model dependent. While this constraint does apply, for example, to the case in which the couplings of the $A$ to SM fermions are the result of mixing with the SM Higgs, there are many other scenarios in which a spin-0 mediator can couple to the SM fermions while having a suppressed coupling to the $Z$.

Several of the constraints shown in Fig.~\ref{fig:spin0med_ps_s} depend on the ratios of the various couplings of the mediator. In particular, since the LHC constraints are dominated by diagrams in which a scalar mediator is produced through a top quark loop, such constraints may be much weaker if the top quark coupling is suppressed. To illustrate this, we plot in \Fig{fig:spin0med_ps_s_tbeta} the derived constraints assuming $\tan \beta  =10$, where $\tan \beta$ is defined as the ratio of the mediator's couplings to down-type and up-type fermions, $\tan \beta  \equiv \lambda_{d} / \lambda_{u}$. While bounds from LEP, LUX and BaBar are not significantly affected by the value of $\tan \beta$, mono-jet+MET bounds can be noticeably reduced, in particular in the case of $\lambda_r \ll 1$. Increasing $\tan \beta$ also reduces the width of the mediator for $m_A > 2 m_t$, potentially opening up additional parameter space.

\end{figure*}

We repeat this exercise in Fig.~\ref{fig:spin0med_ps_ps} for the case of a mediator with pseudoscalar couplings to both the dark matter and to SM fermions. In this case, the dark matter's elastic scattering cross section with nuclei is both spin-dependent and heavily momentum suppressed ($\sigma_{SD} \propto q^4$), making direct detection experiments largely insensitive to these models. The bounds derived from colliders, however, are relatively insensitive to whether SM fermions couple via a scalar or pseudoscalar interaction. We emphasize that, as in the previous case, a large portion of parameter space remains viable for this model, especially should the top-mediator coupling be suppressed.

Next, we consider dark matter in the form of a scalar $\phi$, with a Lagrangian given by:
\begin{equation}
\Lag \supset \left[ a \mu_\phi |\phi|^2 + \sum_{f} y_{f}\bar{f} \lambda_{f p}i \gamma^{5} f \right] A \, ,
\end{equation}
where $a = 1 (1/2)$ for a complex (real) dark matter particle.

The phenomenology of this model is summarized in \Fig{fig:spin0med_scalardm}, for the cases of a complex (left frame) or real (right frame) scalar. LHC signatures for this model are rather different from in the case of fermionic dark matter as the decay of the spin-$0$ mediator to dark matter is heavily suppressed. Instead, the dominant constraint from the LHC results from searches for a Higgs-like particle decaying to $\tau^+\tau^-$. At very large mediators masses, however, ($m_A \gtrsim 600$ GeV), the branching ratio to $\tau^+\tau^-$ is reduced and di-jet resonances become slightly more constraining (this accounts for the dip-like feature appearing in the CMS bound). As in the previous scenarios, LEP bounds on scalar decays to $b\bar{b}$ are very constraining in the region $10 \, \rm{GeV} < m_A < 100$ GeV, but only apply in models in which the mediator couples either directly or indirectly to the $Z$.

\end{figure*}

In the lower frames of \Fig{fig:spin0med_scalardm} , we show how these bounds change if the mediator does not couple to leptons and has an asymmetric coupling to up-like and down-like quarks with $\tan \beta = 2$. This choice can open a window of parameter space for $100 \, {\rm GeV} \lesssim m_A \lesssim 2 m_{t}$, depending on the precise values of $\tan \beta$ and $\lambda_r$.

\caption{\label{fig:spin0med_vectordm} As in previous figures, but for a 50 GeV complex (left) and real (right) vector dark matter candidate which annihilates through a spin-$0$ mediator with a pseudoscalar coupling to SM fermions. In the upper frames, we take the mediator's couplings to be equal for all SM fermions, whereas in the lower frames the mediator does not couple to leptons and $\tan \beta = 10$.}
\end{figure*}

Next, we consider the case of vector dark matter $X^\mu$:
\begin{equation}
\Lag \supset \left[ a \mu_X X^\mu X_\mu^\dagger + \sum_{f} y_{f}\bar{f}  \lambda_{f p}i \gamma^{5} f \right] A \, ,
\end{equation}
where $a = 1 (1/2)$ for a complex (real) dark matter particle.

Constraints on this model are shown in~\Fig{fig:spin0med_vectordm}. The dominant decay mode of the mediator in this model, and thus the most constraining LHC search, depends on the mass of the mediator. For $m_A \simeq 100$ GeV the dominant decay is to dark matter, and thus the most constraining search is that based on mono-jet+MET events. This picture is very different for larger mediator masses, however, for which constraints based on searches for Higgs bosons decaying to $\tau^+\tau^-$ become more stringent. Both of these search channels significantly exclude mediator masses above $100$ GeV in this class of models, for both $\lambda_r = 3$ and $\lambda_r = 1/3$. Similar to in the scalar dark matter case, however, we can relax some of these constraints by suppressing the mediator's couplings to leptons and/or by increasing $\tan \beta$ (as shown in the lower frames of Fig.~\ref{fig:spin0med_vectordm}).

LHC bounds are shown for $\lambda_r = 1/3$ (solid) and $g_{\chi v} = 1$ (i.e.~ $\lambda_r \gg 1$) (dotted).}
\end{figure*}

In this section we consider fermonic dark matter annihilating through the $s$-channel exchange of a spin-$1$ mediator, $V_\mu$, with
Lagrangians of the form~\cite{Berlin:2014tja,Hooper:2014fda}:
\begin{equation}
\Lag \supset \left[ a\bar{\chi}\gamma^\mu(g_{\chi v} + g_{\chi a} \gamma^{5})\chi + \sum_{f}\bar{f}\gamma^\mu(g_{f v} + g_{f a} \gamma^{5})f \right] V_\mu \, ,
\end{equation}
where $a = 1 (1/2)$ for a Dirac (Majorana) dark matter candidate. For the case of comparable couplings to various SM fermions this class of models require a $\simeq 35$ GeV dark matter candidate to generate a signal consistent with the Galactic Center excess. Unless stated otherwise, we will adopt this value for the dark matter mass throughout this section.

We begin in Fig.~\ref{fig:spin1med_av_av} by considering the constraints on a Dirac (left) and Majorana (right) dark matter candidate that annihilates through a mediator with purely axial couplings. As spin-dependent elastic scattering with nuclei is unsuppressed in this class of models\footnote{At the nuclear scale, one would in general expect vector couplings to arise at the one-loop level, leading to stronger direct detection bounds~\cite{DEramo:2016gos}. It may be possible to avoid this in some models, however, and thus we conservatively plot direct detection bounds assuming only axial couplings.}, current LUX constraints force such models to either live on resonance ($m_{\chi} \simeq m_V/2$), or have a mediator mass $m_V < m_\chi$ and with $\lambda_r \gg 1$. LHC constraints on this model from searches for di-lepton resonances ($m_V > 400$ GeV) and mono-jet+MET searches ($100 \, {\rm GeV} < m_V < 400$ GeV) limit mediator masses in this model to be below $\simeq 100$ GeV. LHC bounds are shown in this figure for $\lambda_r = 1/3$ (solid) and $g_{\chi v} = 1$ (i.e.~ $\lambda_r \gg 1$) (dotted). Collider constraints for this model are difficult to evade as they do not rely exclusively on couplings to leptons or to specific species of quarks. Such bounds could be evaded, however, if the mediator were to couple exclusively to third generation quarks. An example of such a model is shown in the left frame of \Fig{fig:spin1med_vv_vav}, where we consider a $50$ GeV Dirac dark matter candidate that annihilates through a spin-1 mediator with vector couplings to both dark matter and $b$-quarks (and possibly also $t$-quarks). While the leading order elastic scattering diagram arises at loop level in this case, the vector coupling leads to stringent constraints from direct detection experiments. The dominant constraints from the LHC on vector mediated models typically arise from searches for mono-jet+MET events and di-lepton resonances. Since the production of the vector mediator is in most cases dominated by valence quarks, however, the sensitivity of collider searches is heavily suppressed and thus do not probe significant parameter space in this model. We do not show any LHC constraints in this figure.

In the right panel of \Fig{fig:spin1med_vv_vav}, we consider the phenomenology of models where the mediator couples to Dirac dark matter and fermions with a vector and an axial coupling, respectively. The elastic scattering cross section in this case is both spin-dependent and momentum suppressed, and thus such experiments have only recently begun probing this model. LHC constraints from di-lepton resonances ($m_V > 400$ GeV) and mono-jet+MET searches ($100 \, \rm{GeV} < m_V < 400$ GeV) are, as before, extremely constraining. That being said, di-lepton constraints can be easily avoided if the mediator couples only to quarks, and mono-jet constraints can be significantly relaxed if the mediator couples, for example, only to the third generation. LHC bounds are shown for $\lambda_r = 1/3$ (solid) and $g_{\chi v} = 1$ (i.e.~ $\lambda_r \gg 1$) (dotted).

\section{Dark Matter Annihilating Through $t$-Channel Mediators}

Finally, we consider four scenarios in which the dark matter annihilates through the $t$-channel exchange of a colored and electrically charged mediator to $b\bar{b}$~\cite{Batell:2013zwa,Agrawal:2011ze,Agrawal:2014una}. These cases consist of a Dirac dark matter candidate, $\chi$, and spin-$0$ mediator, $A$:
\begin{equation}
\Lag \supset \lambda_{\chi} \bar{\chi}(1 + \gamma^{5})f A + \lambda_{\chi} \bar{f}(1- \gamma^{5})\chi A^\dagger \, ,
\end{equation}
a Dirac dark matter candidate, $\chi$, and a spin-$1$ mediator, $V_\mu$:
\begin{equation}\label{eq:tchan_Dirac_vec}
\Lag \supset g_{\chi} \bar{\chi}\gamma^\mu(1 + \gamma^{5})f V_\mu + g_{\chi} \bar{f} \gamma^\mu (1 - \gamma^{5})\chi V_\mu^\dagger \,
\end{equation}
and a real or complex vector dark matter candidate, $X_\mu$, with a fermionic mediator, $\psi$:
\begin{equation}\label{eq:tchan_vec_dm}
\Lag \supset g_X\bar{\psi}\gamma^\mu(1 + \gamma^{5})f X_\mu^\dagger + g_X \bar{f}\gamma^\mu(1 - \gamma^{5})\psi X_\mu \, .
\end{equation}

Note that we consider these specific combinations of scalar and pseudoscalar or vector and axial couplings as they are the only examples for which the scalar contact interaction with nuclei is supressed. Instead, elastic scattering occurs in each of these models through a loop-suppressed vector coupling~\cite{Berlin:2014tja,Agrawal:2014una,Agrawal:2010fh}.

In Fig.~\ref{fig:tchannel_sbottom}, we summarize the phenomenology of this class of models. In the upper left frame we consider the case of a Dirac dark matter particle and spin-0 mediator.
In the remaining frames of this figure, we summarize the phenomenology of models with a Dirac dark matter candidate and a vector mediator (upper right), a complex vector dark matter candidate with a fermonic mediator (lower left), or a a real vector dark matter candidate with a fermonic mediator (lower right). In each case, we find that the combination of constraints from the CMS sbottom search and LUX exclude the entire parameter space of this class of models. We also note that the scenarios with a vector dark matter candidate are rather unphysical over much of the parameter space shown due to the very large  width of the mediator.

In the lower left (right) frame, the dark matter is a real (complex) vector, mediated by a Dirac fermion. The entire parameter space of these models is ruled out by the combined results of LUX and sbottom searches at the LHC.}
\end{figure*}

\newpage

\section{Summary and Conclusions}

In this study, we have revisited the range of dark matter scenarios that could potentially generate the observed characteristics of the Galactic Center gamma-ray excess, without conflicting with any constraints from colliders or direct detection experiments. We have taken a simplified models approach, considering the 16 scenarios that were previously found to be viable in Ref.~\cite{Berlin:2014tja} (and listed in Table~\ref{table1}).  Each of these models features a low-velocity dark matter annihilation cross section that is unsuppressed (i.e.~ $s$-wave), and was found to be consistent with all constraints as of 2014. Note that we have not considered any hidden sector models (i.e.~ models in which the dark matter annihilates into unstable particles without sizable couplings to the Standard Model) which, although potentially viable~\cite{Abdullah:2014lla,Martin:2014sxa,Hooper:2012cw}, are beyond the scope of this work.

The main results of this study can be summarized as follows:
\begin{itemize}
\item{Scalar, fermonic, or vector dark matter that annihilates through a mediator with pseudoscalar couplings can in many cases evade all current constraints, for mediator masses between $\sim$10 GeV and several hundred GeV.}
\item{Dark matter that annihilates through a spin-1 mediator is ruled out by the results of LUX/PandaX-II unless the mass of the mediator is approximately equal to twice the mass of the dark matter (near an annihilation resonance). An exception to this conclusion is found in the case of a mediator with a purely vector coupling to the dark matter and a purely axial coupling to Standard Model fermions, which is potentially viable for mediator masses between roughly $\sim1$ GeV and 200 GeV.}
\item{All scenarios in which the dark matter annihilates through a $t$-channel process are now ruled out by a combination of constraints from LUX/PandaX-II and the LHC.}
\item{Constraints from LEP-II and BaBar restrict many of the pseudoscalar mediated scenarios considered in this study. In particular, mediators with a mass in the $\sim$10-100 GeV range are often ruled out by LEP if they couple significantly to the Standard Model $Z$ (such as in scenarios in which the mediator obtains its couplings to Standard Model fermions through mixing with the Higgs).}
\end{itemize}

Dark matter scenarios that are capable of generating the Galactic Center excess are now significantly more constrained than they were even a few years ago. As the sensitivity of XENON1T, LZ and other direct detection experiments, as well as the LHC, continues to improve, either a discovery will be made, or the vast majority of the currently viable parameter space identified in this study will be excluded. If such searches do advance without the appearance of new signals, hidden sector scenarios will become increasingly attractive, in particular within the context of the Galactic Center.

In the Continuum
Danai Gurira and Nikkole Salter
The Perry Street Theater, New York
Production photo
Perhaps the most heartbreaking moment in In the Continuum is when a nurse announces, "Drugs - we don't have those here". To an AIDS patient in Zimbabwe, this is the equivalent to adding a course in torture to their death sentence.
This play is unusual in many ways. Like the writers of Matt and Ben, seen here two years ago, Danai Gurira and Nikkole Salter are talented, young character actresses who have written and performed their own piece, which they developed while still students at NYU less than two years ago.
The reason that In the Continuum is so powerful is the pairing and counterpointing of what might have been two interesting solo shows looking at the impact of this fatal disease on individual women in different cultures and, by extension, on millions of others.
Nia is a nineteen year old American living in LA. This sometime poet has already had trouble with the law but is the envy of her friends because she is dating Darnell, a gorgeous basketball player who seems destined for fame, fortune and maybe even the Lakers.
Zimbabwean Abigail could hardly be more different. She is an upwardly-mobile newsreader for ZBC (or dead BC as it is colloquially known). She is happily married to a successful businessman, Stanford, and they have an intelligent little boy.
What brings these two women together, at least theatrically, is a commonality of experience. Both have unfaithful men, they get pregnant simultaneously and disbelievingly discover that they are HIV positive. This occurs in a memorable scene that crosses continents and, with its perfect timing, owes much to clever direction from Robert O'Hara.
In addition to the protagonists, the actresses play many parts, including family and friends, colleagues and - perhaps most significantly - the nurse in Zimbabwe and Nia's irritatingly philosophical probation officer.
Where the writer-performers score most highly is in Nia's and Abigail's reactions to the devastating news and later developments. Both are initially shocked and angry once the information has sunk in. They also go into a strange kind of societal denial, where even though neither has done anything wrong, they cannot publicly come out and announce their affliction.
When they do so, they also have to admit that their wonderful men are not paragons but have been sleeping around without protection and probably knew that they were infected. The consequence for these women and their unborn children is terrible but one imagines neither man felt any great remorse.
In some ways, the play's tone is reminiscent of the work of another African-American, Dael Orlandersmith particularly in The Gimmick. That show made it across the Atlantic, becoming a big hit in Edinburgh and British audiences would welcome this play, if they get the chance.
It could also be an inspiration to young writers and to producers there, as the idea of new graduates getting a professional production of their play is almost unimaginable in Britain.
The multi-talented Danai Gurira and Nikkole Salter, as Abigail and Nia respectively, deserve to win best newcomer awards for this Off-Broadway production, which has transferred from Primary Stages at 59E59.
The pacing is not always perfect and one or two superfluous characters take focus away from the main storylines but In the Continuum is a powerful and important piece of political theatre that combines serious drama with comic moments and should be seen.

Box Office: 'Divergent Series: Allegiant' Stalls; 'Zootopia' Set to Cross $200M in U.S.
'Allegiant — Part 1' is coming in well behind the first two films; faith-based offering 'Miracles From Heaven' earns A+ CinemaScore.
The Divergent Series: Allegiant — Part 1 is pacing well behind the first two films in its North American box-office debut, while Disney Animation Studios' Zootopia continues to dazzle in its third outing.
Starring Shailene Woodley and Theo James, the Lionsgate/Summit movie earned $11.9 million from 3,740 theaters on Friday, compared to $21.1 million for Insurgent a year ago and $22.8 million for Divergent two years ago. Friday's gross included $2.4 million in Thursday-night previews.
Allegiant, costing north of $100 million to make, is projected to gross $30 million for the weekend; Insurgent debuted to $52.3 million, and Divergent, $54.6 million. The third installment is likely getting dinged by poor reviews and a B CinemaScore (the first two earned an A and an A-).
Allegiant did beat Zootopia on Friday, but Zootopia will pull ahead on Saturday and win the weekend with as much as $39 million. On Friday, Zootopia took in $9.6 million from 3,959 locations as it prepares to cross the $200 million mark sometime over the weekend in North America. Globally, it's already amassed north of $500 million.
Veronica Roth's third book, Allegiant, is being broken up into two films. The first centers on Tris (Woodley) and Four (James) as they escape beyond the wall that encircles Chicago to finally discover the shocking truth of what lies behind it. Robert Schwentke directed Lionsgate's sci-fi film. It also stars Naomi Watts, Octavia Spencer, Jeff Daniels, Ansel Elgort and Miles Teller.
This weekend's other wide release is Miracles From Heaven, TriStar's faith-based offering starring Jennifer Garner. It opened on Wednesday, and should earn nearly $16 million over the course of its five-day debut. On Friday, the film grossed an estimated $4.1 million from 3,047 theaters.
Directed by Patricia Riggen, the film is based on the memoir of the same name by Christy Beam, whose young daughter, played in the movie by Kylie Rogers, made a miraculous recovery from an incurable disease. Queen Latifah also stars. Joe Roth and minister T.D. Jakes produced Miracles From Heaven for Sony.
Another new player this weekend is The Bronze, starring Melissa Rauch as a foul-mouthed former gymnast. The film debuted more than a year ago at the 2015 Sundance Film Festival but was waylaid when Relativity Media found itself in financial crisis. Sony Pictures Worldwide Acquisitions, which had sold the movie to Relativity in the U.S., extracted the film, with sister company Sony Pictures Classics taking over distribution theaters.
The movie's troubles continue, however. The Bronze, playing in 1,167 theaters, is bombing in its debut and may not clear $400,000 for the weekend.
New titles at the specialty box office include Jeff Nichols' film Midnight Special, starring Michael Shannon and opening in five theaters. The movie is pacing to post a solid location average of $40,000 for the filmmakers and Warner Bros..
March 19, 7:30 a.m. Updated with Friday numbers.

LendInvest named exclusive lender on first phase of new homes project in Kent
Home » News » LendInvest named exclusive lender on first phase of new homes project in Kent
LendInvest has been named the exclusive development finance lender on the first phase of a long-term development scheme that aims to build up to 5,750 new homes outside Dover in Kent.
The borrower, Halsbury Homes, owns a site in Whitfield, four miles from Dover, with plans to build 5,750 homes. Following a competitive process, LendInvest has agreed to fund the construction of 216 units in Richmond Park, the first section of the site to be developed on which Halsbury has consent to build 1,310 homes. This marks LendInvest's largest development project to date, by the number of units under construction.
The developer initially received a LendInvest bridging loan of £10m to repay an existing lender. The borrower subsequently transitioned to a LendInvest development finance loan of £7.75m for construction.
Halsbury also has building consent for further amenities such as a school, shops and a retirement home within Richmond Park. Additionally, the developer has negotiated a new bus route with the local council to run through the site, enhancing accessibility for the new residents.
The development is in a sought-after location for commuters with good transport links to London. Trains to St Pancras International take only one hour five minutes.
The total loan provision for this site is just under £18m based on an LTV of 64%. Construction of the first 216 units is expected to be completed by late 2019 and the total GDV is forecast to exceed £59m.
All of the 216 units funded by this development finance loan will be available for purchase by first time buyers through the government's Help to Buy scheme.
Steve Larkin, director of development at LendInvest, commented:
"Funding a development on the scale of Richmond Park is hugely exciting as a lender. There is great potential for a very long-term relationship and this deal shows how far we have grown as a development finance backer in two years since our development loans were formally launched. The fact that this will be adding at least 216 affordable homes to the country's housing stock in an area that's popular with families and commuters is a significant bonus."
Jason Green, chief financial officer of Halsbury Homes said:
"Whitfield is the second largest regeneration development in Kent and is very important to Halsbury. We have been in the fortunate position of having several funders interested in supporting our next phase of growth. However, once LendInvest showed interest in supporting us on the scheme, it was not a difficult decision to partner with them, as they have been a strong partner to us on other sites.
"This transaction was no different to our previous experiences of working with LendInvest. The team moved quickly through the analysis and diligence phases and completed the loan documentation in a short timeframe. Post-completion, the lending relationship is running very smoothly. We are confident and excited about Whitfield and pleased to be enabling people to move, getting new, first time buyers into the market and doing our bit to help the country solve its major housing problem."
Naismiths advised LendInvest and Halsbury Homes on the transaction.
Blane Perrotton, managing director, Naismiths, added:
"It's not just the scale of this project that makes it special, it's the ambition. The creation of 216 new, affordable homes in such a sought-after location will make Richmond Park a crucial development in the effort to solve Britain's housing crisis.
"Naismiths has successfully partnered with both Halsbury Homes and LendInvest over several years. Our relationships are based on respect, hard work and performance, and we're proud to have served as project monitors on this development from inception right through to construction."

This is beautiful done. Thank you so much!!
Sorry, Sam. Unfortunately, we cannot provide Garbage Collection tuning consulting via our blog. This is not our core business and certainly not the most effective channel.
Thanks, I do understand that. But I just want to know if Minor GC before EDEN getting full is even possible ?
The maxThreshold is set to 9, I see the memory of the objects for all the 9 ages. This means there are 9 Minor GCs happening ???
This is great stuff. I am going through the handbook at the moment. I am so excited to learn from your handbook.
This is amazing. Very clear and detailed explanation.
Would start reading rest of post right now.

Q: regex to remove ANY number/letter combination? It's easy to remove all digits from the following string:
>>> string = "asprx12303 hello my 321 name is Tom 2323dsad843, 657a b879 843aa943 aa... 2ci 2ci"
>>> modified = re.sub(r'\d+', '', string)
>>> print(modified)
'asprx hello my  name is Tom dsad, a b aa aa... ci ci'

But I want to remove every standalone digit (e.g. 321 by itself) and every combination of letters and numbers in the string (e.g. 843aa943 and asprx12303).
This is what I have so far:
>>> modified2 = re.sub(r'\w+\d+', '', string)
>>> print(modified2)
' hello my  name is Tom , a   aa... 2ci 2ci'

So, these two patterns work pretty well, but I'm left with 2ci at the end. How can I make an all-encompassing regex for this issue? My solution is ok so far, but is not quite what I need.

A: Something like this:
r'\w*[0-9]\w*'

That should match any contiguous run of word characters containing at least one digit.

Search engine optimization can be a scary topic for many marketers because it is constantly changing. The search engines regularly update their algorithms and use hundreds of factors to determine how websites rank on millions of keywords and phrases. Many small businesses struggle with the concept of getting to the first page of Google and think that because the bigger companies are always at the top, that must mean that they have no chance to compete. And while much of SEO is based on quantity and quality of relevant content and backlinks from reputable sources, there's one element that local companies can leverage to increase their search rankings – adding local flavor to your website's copy.
Google found that local search traffic pays off for businesses with a narrowly defined geographic footprint. A 2014 study revealed that half of consumers who searched for a local business on their phone visited a store within 24 hours, and nearly 20% of those searches on mobile device led to a purchase. ComScore did their own study and found that nearly 75% of local searches done via a mobile device led to an in-store purchase. The key element to such success? Being found in local search results.
To help get your business in front of local searchers with transactional intent, you'll want to make sure to optimize your website copy for maximum local search appeal. Why? Because it's easier to rank locally than to compete with national brands, and if search engines determine a search has local intent, they will show local companies at the top of the search engine results page. In plain terms, local businesses have a better opportunity to cater to local audiences than national companies by employing strategic copywriting and SEO best practices.
How well known or credible your business is, which can be determined by how many links point to your website from other credible and popular sites. The more credible you are, the higher your domain authority in the eyes of the search engines.
When strategizing the best keywords to incorporate into your site, it's best to start by conducting keyword research based on your company's location. Using keyword planning tools, like Google's free keyword planner, you can discover what terms people search on in a specific geographic area, and create a list of relevant keywords that you'd like to optimize your site around. It's also important to look at your Google Analytics data and Search Console (Webmaster) data to discover keywords are already sending traffic to the site.
Long gone are the days where a site owner could stuff a page with keywords. The search engines are much smarter than that, so site owners must plan for local SEO from the very beginning of a project. Using your list of target keywords, map out your site architecture to maximize SEO ranking opportunities. Create dedicated pages for specific topics that have demonstrated search activity and then look for opportunities to maximize page URLs and site copy to naturally weave in these terms. Search engines want you to first write for users, so be sure to craft natural yet strategic content. Additionally, when optimizing your About Us, Contact Us, Locations, Meet the Team pages, make sure to add city, state, metro information near your prioritized keywords and phrases to maximize local SEO ranking opportunities.
Here are some of the best areas to optimize on-page SEO and suggestions on how to maximize local search results.
A meta description is the page description that appears below your website on the search engine results page. This isn't used to rank websites, but it's what searchers will use to evaluate a web page when performing a search, and deciding on which link best matches their search intent. In 155 characters or less, you'll want to get across what the page is about, what you're selling, the benefits to the user, what differentiates you from the competition, and local context, like a location.
The title element of a page is used to describe what the page is about, in 55 characters, or the amount of text that will fit within 512 pixels. Include your target keyword/phrase in the title tag at least once and keep it closer to the beginning for maximum results. If you can fit in another variation or add local context, bonus points. It's a best practice to include the brand name at the end of the title tag on all pages except the homepage, where you'll want to bump the brand name up to the beginning.
The alt tag is the descriptive tag that's associated with an image in your content management system (CMS). If an image doesn't load on a page, or a screen reader is being used, the alt text will display or be read. The alt text of an image is also what an image search will use to prioritize results, which can sometimes bring valuable traffic to your site. Adding alt text to images is also a recommendation for an ADA conformance, according to WCAG 2.0 guidelines.
When writing your website copy, your keyword research is essential. You will need to infuse target keywords, variations of those keywords and long tail phrases to the body copy of your website and to your headings, or H1, H2s, and H3s. The headings are important areas that crawlers use to understand what your page is about. Think of them as a table of contents for your page. Don't use the same heading on every page, and be sure to inject local geographical terms into these areas when you can. Remember, search engines don't know where your business is unless you tell them. The goal is to strike a balance between writing for humans and bots, so when in doubt, go for the humans.
Another area on your site you can optimize are your URLs. Ideally, a page URL includes the focus keyword to strengthen the relevance to search engines and visitors. Use hyphens to separate words, and concentrate on maximizing the URLs of your location pages. For example, a site selling flea control products for dogs should name a product category page "/dog-flea-control".
If you have many physical locations, it's tempting to simply replace the name of your location on each page and keep the copy the same. Search engines will frown upon this because this copy lacks credibility. Instead, if you can create unique content on each location page, and reference things in that specific geographic area, you'll have a better chance of coming up above your competitors in search. If you have multiple locations, you can even create pages to break up the locations by state or metro. For example, a regional coffee chain can have a page for each shop, mentioning popular menu items and nearby neighborhood finds so that the page feels truly local.
Some of the most important elements of these pages include having a map on the page, click to call functionality enabled on mobile devices for a phone number, a link for directions, and your business NAP, or Name, Address and (local) Phone number. This is becoming more important for mobile and local search and will give your company the edge in the rankings battle. If you are cleaning up your Google My Business or Yelp listings, you'll want to include a link to the individual location page within your listing, not just your homepage. Explore additional tips for how to optimize your listings in this related ZAG Interactive blog.
Another place to add local flavor to your website copywriting to improve your search rankings is within any testimonials or case studies. These can be added directly to your location pages or sprinkled throughout your website. Wherever they appear, consider adding not only the first name and last initial of your customer, but the town and state that they are from. A local business in Sheboygan Wisconsin adds more search engine credibility when customers like "Fred H, Sheboygan, WI" and " Wilma, Sheboygan, WI" have lovely, local testimonial quotes.
A great way to improve your SEO strategy is to add a blog or resource center to your site, and post quality content frequently. Once you have this set up, add local flavor to your blog posts. Some ideas for blog posts include talking about local events the company attended or is sponsoring, or the charity and non-profit partners that you are helping in the area. You can also comment on local news and include stories from your customers and how you helped. If you are providing educational content, add local elements that may pertain to what you're selling. Also, think about what questions your customers ask, and answer them. Chances are if one person asked, then others have the same question, but don't have the nerve or time to ask.
Try to put a local spin on these posts by using research tools and common sense. For example, if you type a phrase into Google and see related phrases appear, those are the most common search queries. This can be a simple way to conjure up topics for your blog, resource center or content marketing strategy.
Notice how a state name came up in this simple search?
When writing your site's copy, try to work in relevant things about the culture and the area, and add geographical terms in areas including your title tags, headings, body copy, URLs, location pages, blog posts and product pages. If you aren't sure where to start, it's a great idea to get an outside perspective and ask for an SEO audit to see what areas of your website could be optimized and revised. Then work with a skilled copywriter and digital strategist to put together a plan for how to refresh your site and continuously add to it.

Ensuring Freshness of Seafood at The Dock by Thammachart Seafood
Bangkok (Thailand) – Otober 10, 2018 (travelindex.com) – Founded in 2008 by Julian G. Davies and Yeeran G. Davies, Thammachart Seafood is now the largest operator of seafood counters in Thailand with over 155 outlets and 600 staff members throughout the country. Created due to the high demand in the local retail market for fresh, imported seafood, the owners contributed their background as a seafood producer in the formation of the company.
Julian and Yeeran visit as many aquaculture and wild fisheries as possible to work directly with farm owners, thus streamlining the supply chain and ensuring seafood freshness. "We know exactly how to choose and what to ask because we used to be the producer ourselves," says Yeeran. There is no middleman in the supply chain for all key products, meaning that farmers are paid a good price for high-quality produce. "As a direct importer of seafood, we are in the position to shorten the supply chain as much as we can, and that's key in our business," says Julian.
Integrity within the supply chain is critical for Thammachart Seafood. All products are traceable, clearly labeled according to their true country of origin and stamped with a use-by date. The company follows a first-in-first-out inventory process, ensuring freshness and correct use. Storage temperature is also essential, and is maintained below 5°c at all times. Importing from over 18 countries, the company has no limitations to add new origins.
The Dock Seafood Bar by Thammachart Seafood
From Dock to Dish
In 2013, Thammachart Seafood branched out to the F&B sector, launching its first seafood bar The Dock in Siam Paragon's Gourmet Market. Inspired by Harrods' seafood bar in London, The Dock differentiates itself with live and fresh products flown in within 48 hours of catching.
"We pride ourselves as Thailand's freshest seafood provider. 48 hours from the dock to the dish is our commitment to the customers to show that we are serious about what we are promising, and we make sure that the products are fresh," says Julian.
The Dock follows a cooking philosophy that focuses on the freshness of the products. Committed to simple seafood preparations that allow the product to shine, sauces are used only to enhance the flavours and never to overpower the dish. "For every dish, we want the product
to come out first, the product must shine. If the customer orders scallop, they must taste the
scallops first before the sauce," says Yeeran.
The Dock Seafood Platter
A sharing platter for those who seek to explore fresh seafood with simple preparations. Served fresh from the live tanks are Cornish Crab, Spencer Gulf King Prawns, and Oysters from all around the world. A Sashimi platter of Tuna, Atlantic Salmon, and King Scallop seamlessly completes The Dock journey.
Tsar of Ō r a King Salm on a l a Minute
The epitome of salmon, some refer to the Ōra King as the wagyu of salmon. Exclusively imported by Thammachart Seafood, the thicker loin cut is used to showcase the exquisite freshness of the fish by smoking it quickly for one minute. As a result, customers can taste the juicy meat in the middle, the smoked belly part, and topped off with the crispy roasted skin.
Red King Crab Au Gratin
An ideal choice for crab lovers, this dish offers the customers a chance to enjoy the whole king crab The Dock's way. Prepared by removing all the juicy meat from the shell, leaving the legs and claws untouched. The meat is baked with Parmesan and cream, topped with Alaskan salmon roe for supreme flavor, while the leg part is steamed without any flavouring – simply the best of both worlds.
Dover Sole à la Meunière
Cooked with butter and wine, this French dish highlights the freshness of the Dover Sole from Holland. Pan roasted in a meunière of butter and parsley then finished off with a hint of lemon, the simple cooking allows the fish to shine without too much flavouring.
The Dock Seafood Bars & Restaurants
The Dock Seafood Bars are now available 6 stores in the Gourmet Markets at Siam Paragon, Emporium, EmQuartier, Bluport Huahin, The Mall Bangkae and its first standalone restaurant was open at Maze Thonglor. A three-tiered oyster tank alongside a fresh seafood bar and a vibrant open kitchen are what best characterises The Dock. Signature to The Dock is the live oyster tank, imported from Australia to keep 10-15 varieties of oysters from around the world in a state of hibernation to maintain the product quality. The EmQuartier and Thonglor outlets also have a second shellfish tank where the water temperature can be reduced to 7°c to keep cold- water Alaskan King Crabs, Lobsters and Geoducks fresh. Customers can select these live
items from the tank, discuss the cooking method with the chef, and simply pay by weight. Each dish on the menu has a wine pairing suggestion, allowing for a complete dining experience.
Dine at the Thonglor venue and choose either the outdoor table seating, indoor table seating or sit at our signature bar to witness the chef's preparation of cold dishes. The new Dock Market is another exciting addition to the restaurant's expanding empire. For aspiring chefs, the long, colorful display with countless varieties of seafood is a dream come true. Peruse the aisles for your favorite ingredients, as well as those you've never even seen before, or, if cooking isn't your thing, simply ask one of the waiting chefs to cook whatever takes your fancy, just as you like it.


The path to success always said is not an appealing one because they're times you would want to give up on your dreams. However, it takes God, focus, hard work and determination to ensure you don't give up on the way.

Behind the Ora ïto brand is a creative young French designer whose provocative ideas ensured his rapid assent to the very top of the design world. At the beginning of his career he presented his designs and ideas for the virtual products, undersigned by known brands on his own website. People began ordering products which did not exist. Large companies like Louis Vuitton, Nike, Gucci, Swatch, Apple and Levi's, could have sued the young pretender but were so impressed by his designs, that they hired him instead.

I'm no original thinker on this, (okay, okay, I confess, I'm a shameless copycat!) but after seeing Carlene's old photographs wearing masks at Organized Clutter, I knew I had to give it a try in my simple attempt to play along at Halloween.
Let me just admit that I'm usually a Halloween stick in the mud. I have been for years now. Fall just whisks by with me rarely succumbing to the slightest bit of decorating or celebration of the changing season, and I especially ignore Halloween. Somewhere along the line, I guess when my kids grew up, I gave up Halloween with all the pressure of costume deadlines and having to open the door to large man-sized guys wearing black capes with their heads and faces and covered with hoods just because it was Halloween. I sure did love going trick or treating as a kid, but that love didn't follow me into adulthood.
This year, however, with the pressure off from costumes, and ever since the Great Pickle came to grace the wall of my dining room, and pumpkins came home with us from the pumpkin patch, my attitude shifted a bit and I decided to get in on the fun and do a little something.
Everyone is headed to the masquerade!
Since this was a free project and one I figured wouldn't require that much of me, I gave it a whirl, choosing a time when Casey was at work to make the masks and get them onto our living room pictures so she would discover them when she came home.
Turns out it was a bit more time consuming than I expected. The big masks were much easier to make than the tiny ones, but cutting out the eye holes was a bear on the little ones! I had no exacto knife within easy reach or it might have been much simpler. And I was making up some of my own patterns to get the correct sizes and working at lightning speed to get done before Casey walked through the door.
Unamused by the eye dressings I gave her?
I downloaded some masks I found online and tried copying Carlene's masks as well because I wanted a variety. I managed to copy a Batman mask for my son and my nephew and made a couple of different ones for everyone else. Some worked in the sizes I originally made them, but others had to be reworked to fit the faces. One of the masks has a kind of Cat Woman vibe to it. I guess that fits since we have Batman in the mix.
After I got these underway, I also saw THIS by Tracy at Crows Feet Chic. These hats would be another fun addition to framed pictures. "The Oak Gulch Ladies' Aid Society;" they look positively witchy! Tracy's going to be decorating for a Halloween party, so check back with her to see what she comes up with! I'm betting it'll be spooky good fun!
Well, I'm pretty excited; today the washer arrives. (We didn't get a dryer yet after all. Too expensive. I didn't want to wipe out every penny I had, so we are going to wait on that.) I spent my evening last night after work clearing a path to where the washer goes from the storage area that once was a garage before we added a room in most of it. This involved lots of shuffling of stuff and piling things up precariously, both in the storage space and in the craft room and the adjacent bathroom. It was quite a feat, but since I wouldn't buy washer hoses (since I already had them), I was told the delivery guy will not bring the washer in and install it. He will only drop it at the door. So I figured I'd better have the simplest way to get it into place without having to go up and down the two steps into the house and then back down a step into the laundry area. That means it will have to go through the usually filled garage storage area, through the usually crammed craft room and through the usually somewhat blocked hall...the stuff has to go somewhere!
Casey and I got this up the one step into the house and then down two steps to the yard. After it sat here a week waiting for trash day, I managed to get it to the road; it was on wheels but they dug into the dirt and grass and it did not want to budge. It took a whole lot of effort. Within ten minutes of getting it to the road, my next door neighbors came and wrangled it up their side yard to their back yard in an amazing feat of strength, and left it right across from where I had it. We could have just pushed it through the bushes! Ah well, we all got a workout.
So in preparation for the delivery of the new washer, I did some unbelievable arranging of junk last night, and then afterwards, I got ambitious, made a decision (Woo!). I pulled out all 16 of the wood pieces (large cabinet doors) I got for free from a pile on the side of the road a while back and took off as much of the hardware as I could get off and threw the wood away. I know we'll be needing that immediately now that it's in the trash, but it was hogging about 4 feet of space and my plans for it were iffy. Gotta do what you gotta do.
Wildly Original Link Party @ I Gotta Create!
Thanks Liz for the shout out about my eye masks. You are right they aren't that easy to cut out, but you did good. And so many photos!
Love the masks! I'm not much on Halloween either. I do the fall thing, but am not into spooky. I know you'll be so glad to get your washer in its place. Thanks as always for your visit and comment! Hope you have a lovely day.
These are so much fun! Carlene does wonderful stuff and thanks for introducing me to Crow Feet Chic!
Great idea and very creative. I like them very much.
Liz your are a beauty catwoman!!!!!!!!!!!!
What a pretty family you have! And your mask project is adorable. After shunning Halloween for years, fearing I was doing something that didn't honor God, I've made the decision to reclaim the day for the Lord at my home. I may give out candy with encouraging "do not fear" type scripture on it!
I am so proud of you for letting the doors go! I need to let go of stuff and only keep my favorites. Too much stuff is not a good thing. Thanks for being a good example!
Charlene always comes up with great ideas and this is no cute exception. We've been in a letting "go" the last week and a half. Once you set you mind it's easier to do. Good luck with getting you new washer in, what's the hoses got to do with installation? Sounds like PS to me!
I've not done Halloween for years... but I'm like Revi up there... I think everyday is a Gift from God... let it be lived to His Glory.
those masks are so cute!
Glad you're getting a new washer!
The masks on the photos are adorable, Liz.
Poor things- glad you had a helpful neighbor.
You'll enjoy your new washer.
I'm off to see Carlene.
Keep lovin' that pickle sign!
These crack me up, so I'm pinning them.
That is just the cutest idea!
Oh Liz, you know I love these. I adored Carlenes and had to feature her the minute I saw them. I have pics hanging above my stairs of all my grandies. I so wanted to do this but not gonna happen this year. Leaving for Hawaii next week and just too much to do. Trying to do Fall yard clean up before leaving. All of your masks turned out so cute. I love the variety! Thanks for sharing with SYC.
Liz, the masks on the pictures are adorable. I haven't really gotten into the spirit of decorating for Halloween this year BUT this makes me want to. I just love the simplicity of adding the masks and the fun feel it gives...not too Halloweeny but Halloweeny enough. It's a perfect balance. And...how funny that the neighbors ended up with your washer.
Your masked photos are wonderful. What a cute, yet simple way to dress them up for the season. I had to laugh at your decision to throw the cabinet doors away...sounds just like something I'd do to clear out the clutter, but I'd be regretting it as soon as they were gone.
Stopping by to say Hi!!!! What's that old saying "copying" is a form of flattery!! So look at it that you are giving someone a compliment for coming up with the idea. Sounds good doesn't it? They are really cute, and a cool idea not matter who comes up with it.
Loved Carlene's and love your masquerade family! How fun - you're no stick in the mud this year! How funny that your neighbor took your washer after all your hard work!!
I love them!!! Instant Halloween decor!
I probably shouldn't say this out loud, but I'm a Halloween stick in the mud as well. For several years my husband and I would just go out for a long dinner/movie on Halloween so we didn't have to suffer through trick or treat. I didn't even like trick or treating when I was a kid. I think I quit trick or treating in 3rd grade. All that said . . . I do like these masks! Very very cute!
This is absolutely hilarious! Love the masks!!!
Found you through Coastal Charm, and glad I did!
This is such a fun idea! You are a STAR tonight over at I Gotta Create!
