Two-tone (or 2 tone) is a genre of British music that fuses traditional ska with musical elements of punk rock and new wave music. Its name comes from 2 Tone Records, a label founded by Jerry Dammers of The Specials, and references a desire to transcend and defuse racial tensions in Thatcher-era Britain; many two-tone groups, such as The Specials, The Selecter, and The Beat featured a mix of black, white, and multiracial people. Originating in the urban centers in England in the late 1970s, it was part of the second wave of ska music, following on from the first ska music that developed in Jamaica in the 1950s and 1960s, and infused it with punk and new wave textures. Although two-tone's mainstream commercial appeal was largely limited to the UK, it influenced the third wave ska and ska punk movements that developed in the US in the late 1980s and 1990s.

Despite legal protection, birds are still illegally killed across migration routes – particularly in the Mediterranean. Experts are meeting this week in Manila to tackle this and other threats against migratory species.
Bird migration is one of nature's most fascinating charms - but for birds to reach their destinations is becoming ever more difficult. And humans have a lot to do with that.
Every year,about 25 million birds are killed across migration routes in the Mediterranean - whether shot, trapped or glued.
In addition, up to 2 million birds are killed illegally in Northern and Central Europe together with the Caucasus region, a new study conducted by BirdLife International has shown.
Surprisingly, most of the birds are slaughtered for "fun," lead author of the study Anne-Laure Brochet told DW.
In order to further improve law enforcement and raise awareness, illegal bird killings will be on the spotlight at the 12th session of the Conference of the Parties to the Convention on the Conservation of Migratory Species of Wild Animals (CMS COP12) happening this week (October 22 to 28) in Manila, Phillippines.
While for most birds the Mediterranean remains the deadliest part of the route, thousands of waterbirds and raptors also struggle to overcome parts of northern Europe and the Caucasus.
In Azerbaijan alone, up to 900,000 waterbirds may be illegally killed every year, the study concludes. Raptors, or birds of prey, are the bird group with most species affected by illegal killing: 51 out of 52.
Even in countries like Germany, the number of raptors killed remains extremely high.
"In Germany, raptors are the most threatened species – about 50,000 to 100,000 are killed per year," German ornithologist Peter Berthold told DW.
Moreover, seven of the bird species with the largest population killed per year in northern and central Europe and the Caucasus are have the global status threatened or near-threatened, such as the rock partridge or the white-headed duck.
In most areas, the lead driver behind illegal bird killing is hunting as a sport. In that context, raptors become a main target.
"Hunters see raptors as direct competitors for game species such as pheasants," Brochet said.
Raptors can also seen as a hindrance for wind farms – if predators fly in the area, permission may not be granted, Berthol explained.
While taxidermy is globally of minor importance, it is of great concern for raptors in Spain – particularly for rare species.
In the Caucasus, birds are largely caught for food and commercial interests. All kind of bird species are sold along roadside near protected natural areas "under the guise of being 'chickens,' 'geese' or 'domestic ducks,'" BirdLife International reports.
Illegal bird slaughtering is also done to avoid certain birds from feeding on agricultural crops – farmers in northern Europe describe this as "pest control."
Egypt is the most dangerous hotspot for migrating birds – 5 to 10 million birds are killed every year in a trapping zone about 800 kilometers (500 miles) long – the total length of Germany, Berthold pointed out.
However, the CMS points to the Mediterranean area as a successful example of tackling illegal bird killing, based on the work of its Intergovernmental Task Force on Illegal Killing, Taking and Trade of Migratory Birds in the Mediterranean region - created in 2014.
"The task force has been quite successful in raising awareness on the problem and has facilitated international cooperation in the area," Borja Heredia, responsible for birds at the CMS, told DW.
During the conference in Manila, the CMS expects to create a new task force for the East Asian-Australasian Flyway – one of the world's greatest migratory paths – where birds are massively killed and trapped for food and trade.
Despite several laws tackling illegal killing of birds, perpetrators do not respect them.
"The legislation is not properly enforced, and penalties are ridiculous," Heredia said. "If someone is caught hunting illegally, he pays the fine – and is hunting again the next day."
For Brochet, there is a need to work closer with national governments to increase law enforcement and motivate civil society to urge their political leaders to take action. This is exactly what the CMS is working on, Heredia explained.
As a measure to make pressure on governments, experts are working to set a "scoreboard" during the conference in Manila, to evaluate countries on their efforts enforcing laws and protecting the migratory species.
Brochet and Berthold highlight that tackling the illegal killing of birds is essential – but should not belittle greater threats for our flying friends.
"In comparison to the 80s or 90s, there are fewer birds killed – but also fewer birds alive in the world, due mainly to intensive agriculture and habitat degradation," Brochet said.
Stopping illegal killing is important, but improving the situation of heavily weakened breeding populations is even more urgent, Berthol concluded.
Vultures usually don't travel long distances, instead, they rise to expand their field of vision. Their excellent eyesight allows the critically endangered species to scan the landscape below from a relatively static aerial position.
The Common crane is a long distance migrant. Important staging areas exist anywhere from Sweden and Germany to China. The height stated here was recorded above the Himalayas.
The birds also fly over the peaks of the Himalayas on their migratory path. Studies have found that they breathe more deeply and efficiently under low oxygen conditions.
The Whooper swan is the Eurasian counterpart of the North American trumpeter swan. It's also the national bird of Finland, featured on the country's 1 euro coin.
These birds are able to breed in high mountain areas because their eggs have less pores than those of lowland species and don't try out as quickly. The bird's embryos also seem to be genetically predisposed to absorbing particularly large amounts of oxygen.
Bearded vultures are listed as 'near threatened' by the IUCN. And you had better not hunt them, because according to Iranian mythology the birds are a symbol of luck and happiness. Whoever shoots one is supposed to die within forty days.
It was just discovered that these duck-like waterfowls are among the world's highest flying birds. Like many others on this list, they cross the Himalayas to get to their breeding grounds.

\section{Introduction}
Effective field theories (EFTs) are being used to describe the effects
of new heavy particles at low energy in terms of operators
of dimension higher than four.
A well acknowledged advantage of this approach is its generality.
The only model dependence resides
in the light degrees of freedom out of which the EFT is built.
(The symmetries of the EFT are in principle also debatable,
but by now the group of gauge symmetries
$SU(3)_c\times SU(2)_L\times U(1)_Y$ is well established.)
Among other aspects, this choice depends crucially on the
nature of neutrinos. If neutrinos are Majorana,
the simplest assumption is that the infrared (IR) comprises only
the Standard Model (SM) fields. The resulting EFT, known as
SMEFT~\cite{Buchmuller:1985jz,Grzadkowski:2010es}, has been
extensively studied in the recent years; see Ref.~\cite{Brivio:2017vri}
for a fresh review.
If neutrinos are Dirac,
the low-energy sector has to be extended with right-handed~(RH)
singlet fermions. The corresponding EFT
is referred to as $\nu$SMEFT~\cite{delAguila:2008ir,Liao:2016qyd}.
It has also been applied to the case in which the
new RH neutrinos are themselves Majorana, as predicted
in numerous models.
(See Ref.~\cite{Biondini:2013xua} for an EFT
for non-relativistic Majorana neutrinos.)
With the same spirit, other EFTs have considered also new scalars
in the IR; see \textit{e.g.}
Refs.~\cite{Franceschini:2016gxv,Gripaios:2016xuo,Anisha:2019nzx}.

A common feature of all these EFTs is that they predict new
processes that are completely absent in the renormalisable SM.
Many of these processes have not been studied yet experimentally.
These include, among others, rare decays of the top quark
such as $t\to\ell^+\ell^- j$~\cite{Durieux:2014xla,Chala:2018agk}, $t\to b\overline{b} j$~\cite{Banerjee:2018fsx,Chala:2018agk} or the non-resonant $t\to b\ell^+ + E_T^\text{miss}$~\cite{Alcaide:2019pnf} as well as
rare decays of the Higgs boson including $h\to \ell^+\ell^-+4j$~\cite{Caputo:2017pit},
$h\to\gamma(\gamma)+E_T^\text{miss}$~\cite{Butterworth:2019iff}.
(In Ref.~\cite{Bischer:2019ttk}
the constraints on the $\nu$SMEFT operators
arising from low-energy experiments have been derived.)
However, this bottom-up approach is not without drawbacks.
Most importantly, operators other than those triggering the
signals of interest are generally also present (with correlated
coefficients) in concrete ultraviolet (UV) models;
some of them being very constrained.
Likewise, it is hard to prioritise one search over others.

It is therefore desirable that searches motivated
by pure EFT inspection
are also supported by realistic UV models~%
\footnote{We are well aware that ``realistic" is an arguable concept.
Here we adopt the notion that a ``realistic'' UV model should involve less free parameters than the EFT
(which in turn restricts the number of new independent heavy fields),
and that there should not be large cancellations between different couplings of similar size.}.
This exercise requires matching UV models to the EFT, generally
at one loop (at which several of the most interesting and/or
dangerous operators appear often).
In the usual diagrammatic approach,
this process consists of computing tens of
one-light-particle-irreducible off-shell amplitudes in both the
UV and the EFT. This is a very demanding task that in turn
requires knowledge of a full off-shell basis of EFT operators
(only those linked by algebraic identities and integration by
parts being removed) and their relations by equations of motion.
If low energy ($E\ll v$, with $v\sim 246$ GeV
being the Higgs vacuum expectation value)
observables are to be computed,
then the corresponding EFT in the electroweak (EW) symmetry
broken phase must be also known,
as well as its matching to the aforementioned operators.
Renormalisation group evolution (RGE) of the Wilson coefficients
in both EFTs might be also needed.

While several of these points have been already addressed in the
SMEFT~%
\footnote{The first complete set of dimension-six operators was obtained in Ref.~\cite{Buchmuller:1985jz}. Several of them were shown to be related by equations of motion in Ref.~\cite{Grzadkowski:2010es}. The corresponding EFT below the EW symmetry breaking~(EWSB) scale, known as LEFT, was worked out in Ref.~\cite{Jenkins:2017jig}; the tree-level matching of the SMEFT onto the LEFT was also provided in the same article. This computation has been recently performed at one loop in Ref.~\cite{Dekens:2019ept}. Finally, the RGE of the SMEFT and LEFT operators was presented in Refs.~\cite{Jenkins:2013zja,Jenkins:2013wua,Alonso:2013hga} and Ref.~\cite{Jenkins:2017dyc}, respectively.},
very little is known about the $\nu$SMEFT beyond a full (on-shell) basis of up to dimension-seven operators~\cite{delAguila:2008ir,Aparici:2009fh,Bhattacharya:2015vja,Liao:2016qyd}. Moreover, while
new techniques~\cite{Henning:2014wua,Henning:2016lyp,Ellis:2016enq,Fuentes-Martin:2016uol,Zhang:2016pja,Ellis:2017jns}
and tools~\cite{delAguila:2016zcb,Criado:2017khh,Bakshi:2018ics,Brivio:2019irc}
for one-loop matching are also being developed,
a severe obstacle for progress in this respect
is precisely the lack of explicit one-loop matching
computations to which compare to in the literature~\cite{Brivio:2019irc}. (To the best of our knowledge, partial examples of one-loop
matching have been only provided for the SM extended with a real scalar singlet~\cite{Boggia:2016asg,Ellis:2017jns,Jiang:2018pbd}, with a charged scalar singlet~\cite{Bilenky:1993bt}, with some colourless EW multiplets for very particular parameters~\cite{Henning:2014wua} and with a vector-like quark singlet~\cite{delAguila:2016zcb}.)

In light of the discussion above, in this paper we consider
a simple UV model whose EFT description is the $\nu$SMEFT,
for which we provide a full off-shell basis
and relations between different operators
by equations of motion; see Section~\ref{sec:model}.
In Section~\ref{sec:matching} we perform
the actual one-loop matching using the diagrammatic approach.
We provide mathematical tools used and details of loop computations
in Appendix~\ref{app:tools} and in Appendices~\ref{app:UV} and
~\ref{app:dim4}, respectively.
In Section~\ref{sec:pheno}  we study the phenomenology
of the resulting EFT (with operators with correlated Wilson
coefficients, as they depend on only
a very small number of UV couplings),
both in the Majorana and in the Dirac cases, and highlight
the importance of performing new Higgs searches at the LHC.
To this aim, we also rely on a full on-shell basis
of the EFT below the EW scale and its matching onto the $\nu$SMEFT,
as well as on partial RGE,
all of which we provide in Appendix~\ref{app:left}.

\section{Model and effective description}
\label{sec:model}
We consider the SM extended with a light RH fermionic singlet $N$, as well as two heavy vector-like fermions $X_E\sim
(\mathbf{1}, \mathbf{2})_{1/2}$, $X_N\sim (\mathbf{1}, \mathbf{1})_1$ and a heavy
singly-charged scalar $\varphi\sim (\mathbf{1},\mathbf{1})_{-1}$.
The numbers within parentheses and the subindex indicate the
representations of $(SU(3)_c, SU(2)_L)$ and the hypercharge $Y$, respectively.
Relatively heavy vector-like fermions and/or charged
scalars and (one or more) sterile neutrinos
are present in a number of models
motivated either phenomenologically
(\textit{e.g.} by the persistent discrepancy between the measured value
of the muon anomalous magnetic moment
and the corresponding SM prediction~\cite{Kannike:2011ng,Dermisek:2013gta,deJesus:2020upp})
or theoretically (\textit{e.g.} in models assuming
left-right symmetry~\cite{Joshi:1991yn,Guadagnoli:2011id,Mohapatra:2014qva},
grand unification~\cite{Fonseca:2015aoa} or
compositeness~\cite{Chala:2012af,Cacciapaglia:2018avr}~---~in this latter
case vector-like fermions are strictly  required by the partial compositeness
paradigm~\cite{Kaplan:1991dc}.)

We assume CP and baryon number conservation,
while lepton number and lepton flavour are only broken by the small
(potentially vanishing) $N$ mass; $N$ is assumed to couple only to the electron
(or to the muon; this choice does not alter our phenomenological results).
Moreover, we assume that the heavy fields are odd under a $\mathbb{Z}_2$ symmetry under which all SM fields
as well as $N$ are even.

We denote by $e, u, d$ the RH leptons and quarks;
and by $L, Q$ the left-handed counterparts.
We name the gluon and the EW gauge bosons by $G$ and $W, B$,
respectively. Let us call the Higgs doublet by
$H = [G^+, (h+iG^0)/\sqrt{2}]$ and $\tilde{H} = i\sigma_2 H^*$,
with $\sigma_I$, $I=1,2,3$, being the Pauli matrices.
The Lagrangian of this model reads:
\begin{equation}
\mathcal{L} = \mathcal{L}_{SM+N}+\mathcal{L}_\mathrm{heavy}\,,
\end{equation}
with
\begin{align}
 %
 \mathcal{L}_{SM+N} &= -\frac{1}{4}G_{\mu\nu}^A G^{A \mu\nu} -\frac{1}{4} W_{\mu\nu}^I W^{I \mu\nu} -\frac{1}{4}B_{\mu\nu}B^{\mu\nu} \nonumber\\
 %
 &\phantom{{}={}}+ \left(D_\mu H\right)^\dagger \left(D^\mu H\right) + \mu_H^2 H^\dagger H -\frac{1}{2}\lambda_H \left(H^\dagger H\right)^2\nonumber\\
 %
 &\phantom{{}={}}+i\left(\overline{Q}\slashed{D} Q + \overline{u}\slashed{D} u + \overline{d}\slashed{D} d + \overline{L}\slashed{D} L +\overline{e}\slashed{D} e +\overline{N}\slashed{D}N\right) \nonumber\\
 %
 &\phantom{{}={}}-\left[\frac{1}{2} m_N \overline{N^c}N + \overline{Q} Y_d H d + \overline{Q} Y_u \tilde{H}u + \overline{L}Y_e H e + \overline{L} Y_N\tilde{H} N + \mathrm{h.c.}\right],
 %
\end{align}
and
\begin{align}
 %
 \mathcal{L}_\mathrm{heavy} &= \overline{X_E}\left(i\slashed{D}-M_{X_E}\right)X_E + \overline{X_N}\left(i\slashed{D}-M_{X_N}\right)X_N \nonumber\\
 %
 &\phantom{{}={}}+\left(D_\mu \varphi\right)^\ast \left(D^\mu \varphi\right)
 -M_\varphi^2\varphi^\ast\varphi
 -\lambda_{\varphi\varphi}\left(\varphi^*\varphi\right)^2
 -\lambda_{\varphi H} \left(\varphi^\ast \varphi\right) \left(H^\dagger H\right) \nonumber\\
 %
 &\phantom{{}={}} + \left[g_X \overline{X_E} \tilde{H} X_N + g_L \overline{X_E}\varphi^* L +
g_N\overline{X_N}\varphi^* N + \text{h.c.}\right].
 %
\end{align}
Our conventions for the covariant derivative of a colour singlet
field $\phi$ and for the EW field strength tensors are
\begin{equation}
 %
 D_\mu\phi = \left(\partial_\mu - i g T^I W^I_\mu - ig' Y B_\mu\right)\phi\,, \\
 %
 \end{equation}
 %
 \begin{equation}
 W_{\mu\nu}^I = \partial_\mu W_\nu^I-\partial_\nu W_\mu^I + g \varepsilon^{IJK} W_\mu^J W_\nu^K\,, \qquad
 %
 B_{\mu\nu} = \partial_\mu B_\nu - \partial_\nu B_\mu\,,
 %
\end{equation}
where $T_I = \sigma_I/2$ are the $SU(2)$ generators.

This model features a number of interesting properties.
\textit{(i)}~Because of the $\mathbb{Z}_2$ symmetry, if the heavy
particles are integrated out,
no effective operators arise at tree level. (Note also that this symmetry
turns the neutral component of $X_E$ into a dark matter candidate, provided
some mechanism at a higher scale~---~which does not modify the results below~---~is invoked
to avoid direct detection constraints; we do not elaborate on this aspect of
the phenomenology though.)
\textit{(ii)}~Because of this, it can be very easily shown that in the IR
only tree-level amplitudes are to be computed while matching at one loop~%
\footnote{Indeed, any one-loop amplitude in the UV and in the EFT would
read $\mathcal{M}_{UV}\sim g_{UV}/(4\pi)^2$ and $\mathcal{M}_{EFT}\sim
\alpha_{EFT}[1 + g_{EFT}/(4\pi)^2]$, respectively. Matching $\mathcal{M}_{UV} =
\mathcal{M}_{EFT}$ implies therefore $$\alpha_{EFT}\sim \frac{g_{UV}}{(4\pi)^2}
\left[1-\frac{g_{EFT}}{(4\pi)^2}\right] =
\frac{g_{UV}}{(4\pi)^2}+\mathcal{O}\left\lbrace\frac{1}{(4\pi)^4}
\right\rbrace.$$ The last term in the right-hand side of the equation is
formally of the same order as two-loop corrections and hence negligible.}.
(Actually, it can be shown that no loops need to be computed in the
EFT even if tree level operators are present, but the proof is more elaborated;
see Ref.~\cite{Manohar:2018aog}.)
\textit{(iii)}~For the very same reason, UV corrections to light
field propagators can be neglected~\cite{delAguila:2016zcb}.
\textit{(iv)}~Likewise, for all practical purposes in the process of matching, any heavy renormalised mass $M$
(evaluated at a scale $\mu$ equal to the physical mass)
can be identified with the physical mass itself.
Finally, for $m_N\neq 0$, this model features also the decay $N\to\nu\gamma$. Any other model fulfilling the
aforementioned properties necessarily involves a larger number of degrees of freedom.

At energies $E < M\equiv \mathrm{min}\left\lbrace M_{X_E}, M_{X_N},
M_{\varphi}\right\rbrace$, this model can be described by a local EFT built upon
the SM fields and $N$, also known as $\nu$SMEFT.
To leading order in the expansion in $E/M$, it is given by $\mathcal{L}_{SM+N}$
(with IR parameters) and a set of
dimension-six operators:
\begin{equation}
 %
 \mathcal{L}_{EFT} = \mathcal{L}_{SM+N}^{IR} + \frac{1}{\Lambda^2}\sum_i
\alpha_i \mathcal{O}_i\,,
 %
\end{equation}
with $\alpha_i$ being dimensionless couplings.
A basis of the operators $\mathcal{O}_i$~%
\footnote{We are not showing explicitly the CP counterparts
of these operators, because we assume CP conservation.
However, they include: $i B_{\mu\nu} (\overline{N}\gamma^\mu\partial^\nu N)$ (the one without $i$, for both the normal field strength and for the dual, is redundant), $i\mathcal{O}_{NB}$, $i\mathcal{O}_{NW}$ (dipole operators with the dual are redundant), $i\mathcal{O}_{LN}^{1,2,3,4}$, $i\mathcal{O}_{LNH}$, $i\mathcal{O}_{HN}$ ($i\mathcal{O}_{NN}^2$ is redundant) and $i\mathcal{O}_{HNe}$. Note that $\partial^\nu\tilde{B}_{\mu\nu}(\overline{N}\gamma^\mu N)$  vanishes due to the Bianchi identity.
On the four-fermion side, we would have $i\mathcal{O}_{duNe}$, $i\mathcal{O}_{LNLe}$, $i\mathcal{O}_{LNQd}$, $i\mathcal{O}_{LdQN}$ and $i\mathcal{O}_{QuNL}$.},
obtained with the help of \texttt{BasisGen}~\cite{Criado:2019ugp}
(see Ref.~\cite{Fonseca:2019yya} for a similar code),
is given in Tabs.~\ref{tab:bosonic} and \ref{tab:fermionic}.
When evaluated on shell, the operators in grey
can be removed from the action by suitable field redefinitions
which, up to dimension-eight effects, can be implemented by using
the equations of motion~\cite{Deans:1978wn,Politzer:1980me,Criado:2018sdb}.
(Redundancies due to algebraic or Fierz identities or integration by parts have
been removed.) Neglecting the small $m_N$ and the Yukawa couplings, the
relevant equations of motion of $\mathcal{L}_{SM+N}$ read:
\begin{align}
 %
 i\slashed{\partial}N &= 0\,,\\
 %
 i\slashed{D}L &=0\,, \\
 %
 (D^2\tilde{H})^i &= \mu_H^2 \tilde{H}^i - \lambda_H (H^\dagger H)\tilde{H}^i\,,\\
 %
 \partial^\nu B_{\nu\mu} &= -\frac{g'}{2} (i H^\dagger D_\mu H + \text{h.c.}) - g' Y^f \overline{f}\gamma_\mu f\,,
 %
\end{align}
where $f$ runs over all SM$+N$ fermions. (The top Yukawa coupling is not negligible; however, its only impact would be the generation of four-fermion operators involving top quarks and $N$, for which there are no sensible searches.)
As a consequence, the following relations hold on shell for the operators in grey:
\begin{align}
 %
 \mathcal{O}_{DN}^1 &= 0\,,\label{eq:odn1} \\
 %
 \mathcal{O}_{DN}^2  &= - \mathcal{O}_{DN}^3\,, \\
 %
   \mathcal{O}_{DN}^3 &= \frac{g'}{2}\mathcal{O}_{HN}  + g' Y^f\mathcal{O}_{fN}\,, \\
 %
 \mathcal{O}_{LN}^1  &= \left(\mu_H^2 \overline{L}\tilde{H}N+\mathrm{h.c.}\right)-\lambda_H \mathcal{O}_{LNH} \,, \\
 %
 \mathcal{O}_{LN}^2  &= - \mathcal{O}_{LN}^3 \,, \\
 %
 \mathcal{O}_{LN}^3  &= \left(\frac{\mu_H^2}{2}\overline{L}\tilde{H}N +\mathrm{h.c.}\right) -
 \frac{\lambda_H}{2}\mathcal{O}_{LNH}
 +\frac{g'}{8}\mathcal{O}_{NB}-\frac{g}{8}\mathcal{O}_{NW}\,, \\
 %
 \mathcal{O}_{LN}^4  &= 0\,, \\
 %
 \mathcal{O}_{NN}^2  &= 0\,. \label{eq:onn2}
 %
\end{align}
As a final remark, let us note that, in light of these equations, effective operators involving $N$ do not generate any purely SMEFT operators upon using the equations of motion.

\section{Matching}
\label{sec:matching}
Hereafter, we assume for simplicity $M_{X_E}=M_{X_N}=M_{\varphi}=M$. Also, we focus on the regime
$g_X\sim g_L\sim \lambda_{\varphi H} \ll g_N$, and $g_N > 1$
(but $\lesssim 4\pi$ to stay in the perturbative regime).
This way, the mass and loop suppression in operators involving $N$
is compensated by the large $g_N$.
On the other hand, purely SMEFT operators can be neglected.

Our process of matching consists of equating one-light-particle-irreducible amplitudes computed in both the UV and the EFT at a scale $\mu=M$ in $\overline{MS}$ with space-time dimension $d = 4-2\epsilon$. Following the discussion above, we only compute those amplitudes involving $N$.
Let us also note that, by virtue of Eq.~\eqref{eq:odn1}, the amplitude involving just two $N$ fields, to which only this operator contributes, does not need to be computed. Likewise, due to the absence of heavy particle couplings to $e$ in the UV Lagrangian, it can be trivially seen that $\alpha_{HNe} = 0$.

The operators $\mathcal{O}_{DN}^{2}$ and $\mathcal{O}_{DN}^3$ can be matched by computing the amplitude
given by the diagrams~%
\footnote{All Feynman diagrams in this article are produced
with the \texttt{Ti\textit{k}Z-Feynman} package \cite{Ellis:2016jkw}.}
$(a)$ and $(b)$ in Fig.~\ref{fig:NNB_and_vNH}.

We use the momentum of the incoming $N$
and the momentum of the $B$, $p_N$ and $p_B$, respectively.
In $\overline{MS}$ we drop terms proportional to
$(1/\epsilon+\log{4\pi}-\gamma)$,
where $\gamma$ is the Euler--Mascheroni constant.
The amplitudes in the UV and in the EFT to order $\mathcal{O}(p^2)$ read:
\begin{align}
 %
 i\mathcal{M}_{UV} = \frac{ig^\prime g_N^2}{96\pi^2 M^2}
 \overline{u}(p_N-p_B)P_L
 \bigg[& \gamma^\mu
 \left(p_B^2 - p_B p_N + \slashed{p}_B \slashed{p}_N\right) \nonumber \\
 %

\end{align}
\begin{align}

 %
\end{align}
We provide all details about the computation of this and the forthcoming UV amplitudes in Appendix~\ref{app:UV}.

The operators $\mathcal{O}_{LN}^1$, $\mathcal{O}_{LN}^2$, $\mathcal{O}_{LN}^3$ and $\mathcal{O}_{LN}^4$, as well as $Y_N$ in the IR, can be matched by computing the amplitude represented by the diagram $(c)$ in Fig.~\ref{fig:NNB_and_vNH}. We take $p_\nu$ and $p_N$ as independent momenta.
To order $\mathcal{O}(p^2)$ we have:
\begin{equation}
 %
 i\mathcal{M}_{UV} = \frac{i g_N g_X g_L}{96\sqrt{2}\pi^2M^2}\overline{u}(p_N) P_L
 \bigg[ 6M^2\left(1-\log{\frac{\mu^2}{M^2}}\right) - p_\nu^2 - p_N^2 + p_{\nu}p_N
 + \slashed{p}_N\slashed{p}_\nu \bigg] u(p_\nu)\,,
 %
 \label{eq:vHN}
 %
\end{equation}
\begin{align}
 %
 i\mathcal{M}_{EFT} = \frac{i}{\sqrt{2}\Lambda^2}\overline{u}(p_N) P_L\bigg[&-Y_N\Lambda^2 - \alpha_{LN}^1 p_\nu^2 + \left(\alpha_{LN}^2-\alpha_{LN}^1-\alpha_{LN}^4\right)p_N^2 \nonumber \\
 %
 &+\left(2\alpha_{LN}^1-\alpha_{LN}^2+\alpha_{LN}^3\right) p_\nu p_N
-\alpha_{LN}^3\slashed{p}_N\slashed{p}_\nu\bigg] u(p_\nu)\,.\label{eq:vHNeft}
 %
\end{align}
The other two operators involving a single Higgs field are $\mathcal{O}_{NB}$ and $\mathcal{O}_{NW}$. They can be matched by computing the amplitude represented by the diagrams in Fig.~\ref{fig:vNAH}.
\begin{figure}[t]
 \centering
 %

 \label{fig:vNAH}
 %
\end{figure}
Taking $p_\gamma$, $p_h$ and $p_N$ as independent momenta,
the results in the UV and in the EFT up to order $\mathcal{O}(p)$ read:
\begin{equation}
 %
 i\mathcal{M}_{UV} =
 \frac{i g_L g_X g_N e}{96\sqrt{2}\pi^2 M^2}\overline{u}(p_N)P_L
 \left[\gamma^\mu\slashed{p}_\gamma - p_\gamma^\mu\right] u(p_\nu) \epsilon_\mu^*(p_\gamma)\,,
 %
\end{equation}
\begin{equation}
 %
 i\mathcal{M}_{EFT} = \frac{\sqrt{2}i}{\Lambda^2}\left(c_W \alpha_{NB} + s_W \alpha_{NW}\right)
 \overline{u}(p_N)P_L
 \left[\gamma^\mu\slashed{p}_\gamma-p_\gamma^\mu\right] u(p_\nu) \epsilon_\mu^*(p_\gamma)\,.
 %
\end{equation}
Here $c_W \equiv \cos \theta_W$ and $s_W \equiv \sin \theta_W$,
with $\theta_W$ being the weak mixing angle.
(Let us emphasise that in our convention, $W^3_\mu = c_W Z_\mu + s_W A_\mu$, $B_\mu = c_W A_\mu - s_W Z_\mu$.)
This amplitude was also computed previously in Ref.~\cite{Butterworth:2019iff} (see appendix therein).
Still, one more amplitude needs to be computed in order to completely fix the Wilson coefficients of the one-Higgs operators.
We choose that represented by the diagram $(a)$ in Fig.~\ref{fig:eNWH_and_NNHH}.
\begin{figure}[t]

(Note that, despite not explicitly shown, diagram~$(b)$ but with the two Higgses exchanged is also present.)}
 \label{fig:eNWH_and_NNHH}
 %
\end{figure}
Taking $p_h$, $p_W$ and $p_N$ as independent momenta, we have to order $\mathcal{O}(p)$:
\begin{equation}
 %
 i\mathcal{M}_{UV} = \frac{i g_N g_X g_L g}{192 \pi^2 M^2}
 \overline{u}(p_N) P_L \bigg[ p_N^\mu - 2p_h^\mu - p_W^\mu - \gamma^\mu
\slashed{p}_N \bigg] u(p_e) \epsilon_\mu^\ast(p_W)\,,\label{eq:eNWh}
 %
\end{equation}
\begin{align}
 %
 i\mathcal{M}_{EFT} = \frac{i g}{2\Lambda^2}\overline{u}(p_N) P_L\bigg[&- \left(\alpha_{LN}^2+\alpha_{LN}^3 \right) p_N^\mu -2\alpha_{LN}^1p_h^\mu -\left(4\frac{\alpha_{NW}}{g}+\alpha_{LN}^1\right)p_W^\mu \nonumber\\
 %
 &+\alpha_{LN}^3\gamma^\mu\slashed{p}_N +
4\frac{\alpha_{NW}}{g}\gamma^\mu\slashed{p}_W \bigg] u(p_e)
\epsilon_\mu^*(p_W)\,.\label{eq:eNWheft}
 %
\end{align}

The operator $\mathcal{O}_{NN}^2$ can be matched by computing the amplitude represented by the diagrams~$(b)$ and $(c)$
in Fig.~\ref{fig:eNWH_and_NNHH},
while the operator $\mathcal{O}_{HN}$ by computing
the diagram $(a)$ in Fig.~\ref{fig:NNHHW3_and_vNHHH}.
\begin{figure}[t]

(Note that, despite not explicitly shown, all these diagrams but with the corresponding Higgs legs exchanged are also present.)}
 \label{fig:NNHHW3_and_vNHHH}
 %
\end{figure}
(It might seem that $\mathcal{O}_{HN}$ also contributes to the former amplitude; however, only its CP counterpart $i\mathcal{O}_{HN}$, which we do not need to consider, does it.)
The first one reads, to order $\mathcal{O}(p)$:
\begin{equation}
 %
 i\mathcal{M}_{UV} = - \frac{ig_N^2 \lambda_{\varphi H}}{96\pi^2M^2}
 \overline{u}(p_{N'}) P_L \left[\slashed{p}_N + \slashed{p}_{N'}\right] u(p_N)\,,
 %
\end{equation}
\begin{equation}
 %
 i\mathcal{M}_{EFT} = \frac{i}{\Lambda^2}\alpha_{NN}^2 \overline{u}(p_{N'}) P_L \left[\slashed{p}_{N} + \slashed{p}_{N'}\right] u(p_N)\,.
 %
\end{equation}
In the UV and EFT to zero momentum, the second aforementioned amplitude reads:
\begin{equation}
 %
 i\mathcal{M}_{UV} = \frac{i g g_N^2 g_{X}^2}{96\pi^2 M^2} \overline{u}(p_{N'}) P_L \gamma^\mu u(p_N) \epsilon_\mu^*(p_{W^3})\,,
\end{equation}
\begin{equation}
 %
 i\mathcal{M}_{EFT} = -\frac{i\alpha_{HN} g}{\Lambda^2} \overline{u}(p_{N'}) P_L \gamma^\mu u(p_N) \epsilon_\mu^*(p_{W^3})\,.
 %
\end{equation}
The operator $\mathcal{O}_{LNH}$ can be matched by computing the amplitude depicted by the diagrams~$(b)$ and $(c)$
in Fig.~\ref{fig:NNHHW3_and_vNHHH}.
To zero momentum, the amplitudes in the UV and in the EFT are given by~\cite{Butterworth:2019iff}:
\begin{equation}
 %
 i\mathcal{M}_{UV} = \frac{i g_N g_X g_L}{32\sqrt{2}\pi^2M^2}
 \left(\lambda_{\varphi H} - g_X^2\right)
 \overline{u}(p_N) P_L  u(p_\nu)\,,
 %
\end{equation}
\begin{equation}
 %
 i\mathcal{M}_{EFT} = \frac{3i\alpha_{LNH}}{\sqrt{2}\Lambda^2}\overline{u}(p_N)P_L u(p_\nu)\,.
 %
\end{equation}

On the side of four-fermion operators, the only such non-vanishing interactions (before using the equations of motion) are $\mathcal{O}_{NN}$ and $\mathcal{O}_{LN}$. They can be matched by computing the amplitudes depicted by the diagrams~$(a)$ and $(b)$
in Fig.~\ref{fig:NNNN_and_NNvv}, respectively.
The UV and EFT expressions for each amplitude
to zero momentum read, respectively:
\begin{equation}
 %
 i\mathcal{M}_{UV} = - \frac{i g_N^4}{96 \pi^2 M^2}
 \left[\overline{u}(p_3)\gamma^\mu P_R u(p_1)\right]
 \left[\overline{u}(p_4)\gamma_\mu P_R u(p_2)\right],
 %
\end{equation}
\begin{equation}
 %
 i\mathcal{M}_{EFT} = \frac{4i\alpha_{NN}}{\Lambda^2}
 \left[\overline{u}(p_3)\gamma^\mu P_R u(p_1)\right]
 \left[\overline{u}(p_4)\gamma_\mu P_R u(p_2)\right],
 %
\end{equation}
and
\begin{equation}
 %
 i\mathcal{M}_{UV} = -\frac{ig_N^2 g_L^2}{192\pi^2 M^2}
 \left[\overline{u}(p_{\nu'})\gamma^\mu P_L u(p_\nu)\right]
 \left[\overline{u}(p_{N'})\gamma_\mu P_R u(p_N)\right],
 %
\end{equation}
\begin{equation}
 %
 i\mathcal{M}_{EFT} = \frac{i\alpha_{LN}}{\Lambda^2}
 \left[\overline{u}(p_{\nu'})\gamma^\mu P_L u(p_\nu)\right]
 \left[\overline{u}(p_{N'})\gamma_\mu P_R u(p_N)\right].

\end{figure}

By equating all UV amplitudes to their IR counterparts,
we end up with 23 equations (including  $\alpha_{HNe}=0$)
for 15 unknowns; the redundancies reflect the gauge
symmetries~\footnote{Note, for example, that the
contributions of $\mathcal{O}_{LN}^1$ to the amplitudes $\langle\nu N h
\rangle$ and $\langle e N W h\rangle$ are correlated, because both the
$\mathcal{O}(p^2)$ Higgs piece as well as the $WH$ interaction come from $D^2\tilde{H}$. Thus, when matching \textit{e.g.} the $p_\nu^2$ part of Eqs.~\eqref{eq:vHN}
and \eqref{eq:vHNeft} one gets $\alpha_{LN}^1 = (g_N g_X g_L)/(96\pi^2)\times
(\Lambda/M)^2$; exactly the same as matching the $p_h^\mu$ piece of
Eqs.~\eqref{eq:eNWh} and \eqref{eq:eNWheft}.}.
Neglecting the running from the scale $\mu=M$ to $\mu=v$, the following identities hold off shell at the EW scale (other Wilson coefficients vanish):
\begin{gather}
 %
 Y_N^{IR} = Y_N^{UV} - \frac{g_L g_X g_N}{16\pi^2}\,, \\
 %
 \begin{align}
 %
 \frac{\alpha_{DN}^2}{\Lambda^2} &= \frac{e g_N^2}{192 \pi^2 c_W M^2}\,, \Label{} &
 %
 \frac{\alpha_{DN}^3}{\Lambda^2} &= \frac{e g_N^2}{96 \pi^2 c_W M^2}\,, \\

 \end{align}

\end{gather}
where $e=\sqrt{4\pi\alpha}$, and $\alpha\approx 1/137$ stands for the electromagnetic fine-structure constant. Finally,
upon using the equations of motion,
Eqs.~\eqref{eq:odn1}--\eqref{eq:onn2},
the following relations hold on shell (other Wilson coefficients vanish):
\begin{gather}
 %
 Y_N^{IR} = Y_N^{UV} - \frac{g_L g_X g_N}{16 \pi^2} \left(1+ \frac{m_h^2}{24 M^2}\right)\,, \label{eq:yn} \\

 %
 \frac{\alpha_{LNH}}{\Lambda^2} &= -\frac{g_L g_X g_N}{192\pi^2 M^2}\left[\frac{m_h^2}{v^2} + 2 (g_X^2-\lambda_{\varphi H})\right]\,, \Label{} \\

 \frac{\alpha_{dN}}{\Lambda^2} &= -\frac{e^2 g_N^2}{576 \pi^2 c_W^2 M^2}\,. \Label{eq:dN}
 %
\end{align*}
\end{gather}
For convenience, let us also define
$\mathcal{O}_{NA} = c_W\mathcal{O}_{NB} + s_W\mathcal{O}_{NW}$
and $ \mathcal{O}_{NZ} =  c_W\mathcal{O}_{NW} -s_W\mathcal{O}_{NB}$.
For the coefficients of these operators we obtain:
\begin{align}
 %
 \frac{\alpha_{NA}}{\Lambda^2} &= \frac{e g_L g_X g_N}{192\pi^2 M^2}\,, \Label{} &
 %
\frac{\alpha_{NZ}}{\Lambda^2} &= \frac{e g_L g_X g_N (1-4s_W^2)}{768 \pi^2 s_W c_W M^2}\,.
 %
\end{align}

Finally, let us emphasise that the coupling constants
of renormalisable operators in the EFT can
also be written in terms of the UV couplings; $g_{IR} =
g_{UV} + g'_{UV}/(16\pi^2)$. However, one can always reabsorb the one-loop
corrections by redefining $g_{UV}\to g_{UV}-g'_{UV}/(16\pi^2)$. This
redefinition would propagate to all $\alpha$ couplings, but the impact would be
formally of two-loop order. Still, for the sake of
completeness, we have computed all renormalisable EFT terms in Appendix
\ref{app:dim4}.

\section{Sterile neutrino phenomenology}
\label{sec:pheno}
In the process of matching we have neglected $m_N$. The only effect of $m_N\ne 0$ would appear in the dimension-five operator $\overline{N^c} N H^\dagger H$ suppressed not only by the loop factor but also by $m_N/M$, namely by $\sim 10^{-3}$ if $m_N\sim 1$ GeV and $M\sim 1$ TeV. (The operator $\overline{N^c}\sigma^{\mu\nu} N B_{\mu\nu}$ vanishes in this case because $N$ is Majorana.) However, $m_N\neq0$ has a huge impact on the phenomenology of $N$, because it allows the latter to decay into $\nu\gamma$. The corresponding decay width must be computed after EWSB, namely in the $\nu$LEFT, obtained first by matching the $\nu$SMEFT at the EW scale and after running down to $\sim m_N$. The full list of $\nu$LEFT operators involving $N$ is given in Tab.~\ref{tab:fermionic2} in Appendix~\ref{app:left}. The operator that triggers the decay of $N$ is $\mathcal{O}_{N\gamma}$. For completeness, though, we provide tree-level matching of all $\nu$SMEFT operators to all $\nu$LEFT ones in Eqs.~\eqref{eq:match1}--\eqref{eq:match2}. The one-loop running of all $\nu$LEFT operators generated in our setup, including $\mathcal{O}_{N\gamma}$, is also given in the same appendix. Altogether, we have:
\begin{equation}
 %
 \Gamma(N\to\nu\gamma) \approx
 \frac{m_N^3 \alpha_{N\gamma}^2(v)}{2\pi v^2}
 \left(1 - \frac{5e^2}{9\pi^2} \log\frac{v}{m_N} \right)^2\,.
 \label{eq:GammaNRG}
 %
\end{equation}
For simplicity, let us fix $Y_N^{UV}$ such that $Y_N^{IR} = \alpha_{LNH} v^2/(2\Lambda^2)$; see Eq.~\eqref{eq:yn}.
This way, the mixing between $N$ and $\nu$ vanishes strictly.
(Note that the sole important effect of this mixing would be inducing a Majorana neutrino dipole moment for $\nu$; this vanishes however in our case due to lepton flavour conservation~\cite{Butterworth:2019iff}.)

Different experiments constrain the parameter space under study.
The relevant observables can be all computed directly in the $\nu$SMEFT. (In quoting the following bounds we have set $\Lambda = 1$ TeV.) We have first $\mathcal{B}(Z\to\nu\nu\gamma\gamma)$. Experimentally it is bounded to be $<3.1\times 10^{-6}$~\cite{Tanabashi:2018oca}. In our context this branching ratio is given by (note that for $m_N \sim 1$~GeV, $\mathcal{B}(N\to\nu\gamma)\approx 1$~\cite{Duarte:2015iba}):
\begin{align}
 %
 \mathcal{B}(Z\to\nu\nu\gamma\gamma) \approx\mathcal{B}(Z\to NN)
 &\approx \frac{1}{\Gamma_Z^{SM}}\frac{m_Z^3 v^2}{24\pi\Lambda^4}\alpha_{HN}^2 \nonumber\\
 %
 &\approx \, 2.7\times 10^{-10} g_N^4
 \left(0.029-g_X^2\right)^2\frac{\text{TeV}^4}{M^4}\,,
 %
\end{align}
with $\Gamma_Z^{SM}\approx 2.5$ GeV.
This bound implies in turn a limit on $\alpha_{HN} < 0.11$, which is ultimately the most stringent constrain on $(M, g_N)$.
Other subleading constraints include: \textit{(i)} $\mathcal{B}(Z\to\nu\nu\gamma)$, experimentally bounded to be $ < 3.2\times 10^{-6}$~\cite{Acciarri:1997im}, which implies $\alpha_{NZ} < 0.081$;
\textit{(ii)} the measurement of the total $W$ boson width, $\Gamma_W^\text{total} = 2.085\pm 0.042$ GeV, which however does not constrain $\alpha_{HNe}$ more than a theoretical perturbativity bound implying $\alpha_{HNe}<4\pi$; \textit{(iii)} the bound on $\alpha_{NA} < 0.88$~\cite{Butterworth:2019iff} as obtained from LHC searches for events with one photon and missing energy~\cite{Sirunyan:2018dsf}.
(Bounds on $\alpha_{NA}$ obtained from the study of differential Drell-Yan distributions at the LHC, mediated by both neutral and charged currents, using \texttt{Contur}~\cite{Butterworth:2016sqg} are weaker~\cite{Butterworth:2019iff}.)
The bound on $\alpha_{NA}$ can be improved to
$\alpha_{NA} < 0.36$ by searches for
$h \to \gamma\gamma + E_T^\text{miss}$,
as proposed in Ref.~\cite{Butterworth:2019iff}.
This value, however, still leads to a very weak constrain on $(M,g_N)$.

Four-fermion interactions could be bounded at the LHC in searches for $pp \to \ell\gamma+ E_T^\text{miss}$. However, we are not aware of any such search; a preliminary phenomenological study has been provided in Ref.~\cite{Duarte:2016caz}.
Interestingly though, it has been shown that searches for Higgs decaying to a single photon and missing energy could test
$\mathcal{B}(h\to \nu N) > 1.2\times 10^{-4}$~\cite{Butterworth:2019iff}.
Noticing that
\begin{align}
 %
 \mathcal{B}(h\to \nu N) &\approx \frac{1}{\Gamma_h^{SM}}
 \frac{m_h v^4}{16\pi\Lambda^4} \alpha_{LNH}^2 \nonumber \\
 %
 &\approx 2.5\times 10^{-6} \left(g_L g_N g_X\right)^2 (0.13 + g_X^2-\lambda_{\varphi H})^2\frac{\text{TeV}^4}{M^4}\,,
\end{align}
with $\Gamma_h^{SM}\approx 4$ MeV,
the corresponding limit on $\alpha_{LNH}$ reads
$\alpha_{LNH} < 7.3\times 10^{-3}$.
We show in Fig.~\ref{fig:constraints} that,
when translated to the plane $(M, g_N)$,
this signal overcomes often the constraint from $\alpha_{HN}$.

 $\lambda_{\varphi H} = -1$, $0$ and $0.5$ (left) as well as
 $\lambda_{\varphi H} = -1$ and $g_X = 0.5$ and $1$ (right).}

If lepton number is exactly conserved,
\textit{i.e.} in particular, $m_N = 0$,
$N$ is just the RH component of the SM neutrino,
which would be Dirac.
In this case, the very stringent bounds on the neutrino
dipole moment~\cite{Canas:2015yoa} can be only satisfied if $g_X\approx 0$ (or $g_L \approx 0$).
Accordingly, only the operator $\mathcal{O}_{HN}$ and
the four-fermions $\mathcal{O}_{LN}$, $\mathcal{O}_{eN}$,
$\mathcal{O}_{QN}$, $\mathcal{O}_{uN}$
and $\mathcal{O}_{dN}$ as well as $\mathcal{O}_{NN}$ could survive,
see Eqs.~\eqref{eq:yn}--\eqref{eq:dN}.
The former enhances the $Z$ decay into invisible,
but the corresponding limit on $(M, g_N)$ is very weak.
Likewise, the bounds on the four-fermion
operators involving quarks and charged leptons are of order
$\alpha/\Lambda^2 \lesssim 1$~TeV$^{-2}$~\cite{Alcaide:2019pnf},
and therefore they are not stringent in this setup
in which all operators arise at loop level,
and hence the effective scale $\Lambda$ is rather
$\Lambda\sim 4\pi M$.

Finally, we are not aware of any significant bound on $\mathcal{O}_{NN}$.
As things stand, this scenario is very much unconstrained
in light of current data, even for $M\sim $ few hundreds GeV.
(In this respect, let us also emphasise that direct LHC searches
for singly charged scalars and vector-like leptons,
which are present in our UV model, do not constrain this range of masses~\cite{Redi:2013pga,Cao:2017ffm,Aaboud:2018jiw,Alcaide:2019kdr}.)

In the lepton number conserving case,
if instead of a single $N$ we have three copies
(in which case all neutrinos would be Dirac), with \textit{a priori}
flavour-generic couplings, the off-diagonal dipole operators would induce
decays of the SM neutrinos, $\nu_j\to\nu_i\gamma$.
For massless neutrino in the final state and neglecting running,
the corresponding decay width reads
\begin{equation}
\Gamma(\nu_j\to\nu_i\gamma) =
\frac{m_j^3 v^2}{8\pi\Lambda^4} \alpha_{NA}^2 =
\frac{m_j^3 v^2}{8\pi M^4} \left(\frac{e g_L g_X g_N}{192\pi^2}\right)^2,
\end{equation}
where $m_j$ is the mass of $\nu_j$.
The lower limit on the neutrino lifetime is $\tau \gtrsim 10^{20}$~s~\cite{Tanabashi:2018oca,Aalberts:2018obr}.
Assuming $m_j \approx 0.1$~eV and $\mathcal{O}(1)$ couplings,
we obtain $M \gtrsim 0.3$~TeV,
and up to $\sqrt{4\pi}$ times
more stringent constraint if $g_N$ is significantly larger than $1$,
as we have been assuming in this work.
Still, as in the previous case, this bound can be avoided if
\textit{e.g.} $g_X\ll 1$.

\section{Conclusions}
\label{sec:conclusions}
In this paper, we have considered a very simple extension of the SM
involving a light RH neutrino $N$ (which can be well the RH part of
any of the SM neutrinos if they are Dirac, or a new Majorana neutrino),
two heavy fermionic fields and one heavy scalar field,
all of them colourless.
In the IR, this theory can be described by the $\nu$SMEFT.
We have shown that, if $N$ is Majorana, new Higgs decays
not yet studied experimentally at the LHC can test this model better
than other studies already performed at low-energy facilities;
most importantly, searches for $Z\to\nu\nu\gamma\gamma$.

We note that, although this observation is relatively straightforward
in the generic EFT, because constrained operators can be set to zero
independently of those triggering the signal of interest,
this is highly non-trivial in the EFT obtained in this model,
in which all Wilson coefficients depend on solely four
arbitrary couplings.
The fact that the signal of interest is not in conflict
with the present constraints in such a simple UV completion
of the $\nu$SMEFT, strengthens the motivation
for novel searches in the Higgs sector.

We have provided a complete calculation of one-loop matching
in the diagrammatic approach, obtained upon computing
the same one-light-particle-irreducible off-shell amplitudes
in the UV and in the IR.
This complements the very few examples of one-loop
matching in the literature, and it is expected that our results
will allow faster progress in the automation of tools
in this respect~\cite{delAguila:2016zcb,Criado:2017khh}.
As a byproduct of this work, we have also obtained a complete
(off-shell) basis in the $\nu$SMEFT, the tree-level matching of the
$\nu$SMEFT onto the low-energy version
(in which the top quark, the Higgs and the $W$ and $Z$ bosons
are integrated out), that we dubbed $\nu$LEFT; as well as
some one-loop anomalous dimensions in the latter EFT.
We leave the computation of the full RGE anomalous dimension matrix in the $\nu$LEFT and in the $\nu$SMEFT for future work.

Hip-hop artist Shane Redway was among the three people who died as the result of a single-vehicle crash near Toronto's Pearson International Airport this weekend.The Toronto Star reported that the collision happened just after 4 a.m. Saturday.The vehicle veered off the highway and hit a guardrail before bursting into flames.Witnesses attempted to rescue the male driver and a female passenger trapped inside, but were only able to pull a second woman from the wreck. She died of her injuries at a hospital later, while the other two people in the car were declared dead at the scene.
CHAMP Management confirmed to the newspaper Redway's death.
"Redway was known for being a passionate artist who was always striving for greatness, pushing the boundaries of always believing in your visions and dreams," the company said in an email statement.
Drake took to Instagram to mourn the loss of his fellow Canadian rapper.
"Gone way too soon. Just saw this guy yesterday at Bounce. RIP Redway," Drake wrote in his post Saturday.

Q: $(\liminf_{n}A_{n})\cap (\limsup_{n}B_{n}) \subset \limsup_{n}(A_{n}\cap B_{n})$ $(A_{n})_{n}$ and $(B_{n})_{n}$ sequences of subsets of $Ω$. Show that:
$$(\liminf A_{n})\cap (\limsup B_{n}) \subset (\limsup A_{n})\cap (\limsup B_{n})$$ and $$(\liminf A_{n})\cap (\limsup B_{n}) \subset \limsup (A_{n}\cap B_{n})$$
I am a bit confused with the set theory but I tried to prove them. I know that $\liminf A_{n} \subset \limsup A_{n}$ so the first part looks easy. For the second part I could use the first one and then I could show that $(\limsup A_{n})\cap (\limsup B_{n}) \subset \limsup (A_{n} \cap B_{n})$ but how can I know if this is always true?

A: $x\in\lim\inf A_n$ means that $x$ belongs to almost all (i.e. all but finitely many) of the sets $A_n$.
$x\in\lim\sup B_n$ means that $x$ belongs to infinitely many of the sets $B_n$.
If $x$ belongs to both, it then means that $x$ also belongs to infinitely many of the sets $A_n\cap B_n$ (precisely the infinitely many sets where $x\in B_n$, minus finitely many of those where $x\not\in A_n$).
This proves that $x\in\lim\sup (A_n\cap B_n)$.

Back in 2006, I founded a television blog called Televisionary (the very one you're reading now).
At the time, it was a little side-project that I stared while working in television development: something to do during the off-hours or (my infrequent) down-time or at my desk during my lunch breaks.
Over the next few years, Televisionary morphed into a full-time job as I watched almost everything on television and cataloged my thoughts, penning reviews, conducting interviews with talent, breaking news, and aggregating the day's entertainment news headlines and major listings every morning. It got noticed by Entertainment Weekly and The New York Times, The Chicago Tribune and CNN, Deadline and Variety.
Televisionary took on a life of its own. It became discussed in Hollywood and I was always surprised to discover that actors or producers or executives who read my TV blog. It was a secret at first, one that I eventually shared with a few friends before spreading outwards, thanks to the advent of social media.
Eventually, Televisionary led me to opportunities with The Los Angeles Times and then The Daily Beast (and a bit later into a joint venture with Newsweek) — where I would serve as television critic and later West Coast Deputy Bureau Chief — and eventually to BuzzFeed, where my title was Entertainment Editorial Director.
Fifteen years ago (!), I had no idea where this blog would take me or the adventures that I would have along the way. The simple act of sitting in front of a computer screen and writing down my thoughts about television led me to some amazing interviews and opportunities. But it all started with an idea.
This is an archive of all of those Televisionary posts during those years — the prolific years, the quiet years, the years where I was experimenting, the years where people were listening and where my words had an effect, the years where I was excited to jump out of bed at 5:30 a.m. and write before work, and the years where it was all I had professionally. This is a record of those times. A different time on the Internet and a different time for me, as a writer, a person, and a human being.

Beauty Shop Insurance. Compare Policies for Best Rates.
As the owner of a beauty parlor, you work hard to make sure that your customers all look their best when they leave your establishment. But how much time do you spend making sure that your business itself is looking its best? An important part of your business should be making sure that you have the right insurance for beauty shops--and that you're paying competitively-priced premiums for your beauty shop insurance coverage.
Shopping around for insurance for beauty shops can be a lot like giving a hair styling to a first-time customer. Before you begin to cut, you look at the shape of your customer's face and ask about her preferences for length and styling. You lift your scissors only after you've done that initial survey.
When you're looking for beauty shop insurance, you'll need to take an objective look at your business to determine just what insurance coverages are appropriate for your particular beauty parlor business. You'll require business property coverages to protect your investment in hair dryers, sinks, cash registers and other equipment used by you and any other stylists that you employ. But if you own your own building, you'll want to make sure that your beauty shop insurance has policy limits high enough to handle any damage to that structure as well.
If you do have stylists working for you, you'll also require workers compensation insurance as part of your insurance for beauty shops coverages. Workers comp will pay for medical treatments for employees injured while on the job and can also provide some replacement income for them if they're too badly injured to return to work right away.
Liability insurance is an important part of beauty shop insurance coverage. General liability insurance will pay for medical care and/or legal bills incurred if a customer injures herself while on your property slipping on a wet floor, for example). But you'll also want professional liability insurance, which kicks in when a service that you provide harms one of your customers like a dye job that causes a severe allergic reaction to your customer). Product liability policies or riders should be part of you insurance for beauty shops coverages as well, since you can be held legally responsible if a shampoo, conditioner or any other product you sell harms the purchaser.
While your customers are willing to pay a fair price for their styling, they don't want to pay more than they have to--just like you don't want to pay more than you have to for insurance for beauty shops coverage. Instead of calling many different agents and filling out many similar forms, try netquote.com. At netquote.com you'll fill out a single form about your business; you'll then get back quotes from several insurance agents who will work with you to get the insurance coverages that you need. Netquote.com offers an attractive solution to finding the right insurance coverages for your beauty shop business.

This course gives a full understanding of how to comply with the Ontario Hours of Service regulations that limit the number of hours drivers can operate commercial vehicles. The course covers application of the rules in city and inter-city operations, as well as sleeper-berth and U.S. operating settings. This course is based on Canadian Trucking Alliance driver handbook "Hours of Service for Commercial Drivers".
Every driver of every commercial vehicle in Canada and the U.S. must comply with rules that restrict when and how long a driver can continue to drive a commercial vehicle.
Single and team drivers using a sleeper berth have additional rules to contend with. Operating in the U.S. means complying with the U.S. rules, and crossing the border involves switching from one set of rules to the other.

Inspection is too late. The quality, good or bad, is already in the product.
Inspection can be useful to gather data on the process. Using that data to see if a process has gone out of control and a special cause needs to be investigated is useful. Using that data to evaluate the success, or failure, of an attempt to improve (via the PDSA cycle) is useful.
Inspecting to pull out the failed items from the production before a customer sees them is a path to failure. If the process is this bad, the process needs to be improved. If you can actually stay in business doing this now, you are at risk for not being able to stay in business when the market stops being willing to pay you to produce results people don't want.
I am reminded of how impressed with Dr. Deming's crediting others. A number of the quotes people credit to Dr. Deming he notes the proper author in his book. I understand that people learn to associate these quotes with Dr. Deming, but I still find it amusing. It also shows his devotion to learning and desire for accurate documentation.
Inspection, as is pointed out, is too late. It might also be noted that inspection does not add value to the product, only cost.
Not mentioned is the problem of inspection that leads to inappropriate "corrective action" such as tampering (changing the process in reaction to a spacial cause). Inspection may show the presence of unacceptable output, but subsequent action must be guided by knowledge of the type of variation present.
I would say the process needs to be improved in any case. This is more in keeping with the idea of continuous improvement. Even if all output meets requirements, the process can be improved, variability can be lessened. The process can be made more robust to outside influences, etc.
In the quote Dr. Deming is discussing the need to improve the capabilities of the process in order to achieve quality. That seeking to achieve quality by inspection of the output and picking out bad output was not the way to get quality into the hands of customers. So this quote related to inspection of the output of the process.
Of course, Dr. Deming also discusses inspection of incoming material in Out of the Crisis and elsewhere. Specifically chapter 15 of Out of the Crisis explores inspection of incoming material.

Expropriating the Lives of the Poor
Posted on August 28, 2018 August 28, 2018 by Dougie Oakes
BETWEEN the 17th and 19th centuries, white – mainly Dutch-speaking – colonialists did not consider legal niceties when they coveted land on which groups of indigenous black people lived.
During white expansion in the 19th century, armed Boer commandoes didn't seek permission. They didn't offer to buy. They didn't negotiate. And they certainly didn't prepare any legal documents under the heading, 'Land Expropriation without Compensation' (or whatever the hell the Dutch translation of this was).
They had a far easier method of getting what they wanted.
Time after time in the interior of Southern Africa, their modus operandi was to shoot dead as many of the black land-dwellers as they could – and then kidnap their children.
And here's something else to remember for those who picture Boer land-grabbers as rough around the edges, but essentially decent and brave pioneers, searching only for sufficient land to set up their own independent countries: the notion of private property was unheard of in African societies. Land belonged to the whole community. It could not be sold or voluntarily ceded by, say, a chief.
Add to this the fact that if it is considered that the main ambition in the area of education for the vast majority of Boers who had trekked from the Cape Colony was to be able to read the Bible, it becomes difficult to understand why they were – and continue to be – given the benefit of so much doubt for the manner in which they acquired land.
The primary method of land acquisition for both Boer and Briton in the first three centuries of colonialism in Southern Africa was theft through the barrel of a gun.
It took more than 240 years for land dispossession to be legalised in the Cape.
In 1894, Cecil John Rhodes introduced the Glen Grey Act to the legislature of the Cape Colony. Its purpose (which the National Party refined and then used 54 years later as the basis for its apartheid policies) was to force black communities off their land and into wage labour.
The Glen Grey legislation was followed in 1913 by the Natives Land Act, which confined African people to just over 7 percent of the land in the Union of South Africa, compared with the just under 93 percent that was set aside for the exclusive use of white people.
In 1936, in terms of the Natives Trust and Land Act, the 7.3 percent of South Africa that was given to African people, was extended to almost 13 percent.
It would be easy to counter the arguments against land restitution without compensation by some newspaper analysts by using these facts alone.
But to do this would let them off the hook far too easily.
Theft is theft, whether it occurred in the 1650s or during the high-noon of apartheid in the 1960s. It should never be forgotten that there was nothing good about the policies of the National Party.
I would like to highlight the specious arguments about the land and property policies of the National Party, by including observations contained in a harrowing book about the forced resettlement of Africans – The Discarded People' – which was written in 1969 by a Roman Catholic priest named Cosmas Desmond. Furthermore, I would like to highlight the effects of the Group Areas Act of 1950 by drawing on my own rites of passage.
But first 'The Discarded People'….
In a foreword describing the living conditions of African people who were forcibly removed from so-called blackspots (around 350 black communities around the country, which were surrounded by white residential or industrial areas), author Nadine Gordimer wrote: 'Our separate development planners have explained at length why communities are moved; what we must not forget is that the important question that can't be answered by any number of demographic maps is how communities live when they are moved.'
She noted too that 'the physical conditions of life described in this book are such an appalling desolation that one is almost unable to think beyond bread and latrines'.
And Desmond wrote: '[T]he vast majority of people are not given any effective choice [about moving]. Firstly, many African people are so conditioned that they take any proposal from a government official as a command. 'Secondly, they know that if they do not "agree" to move they will be liable to prosecution.'
He gave as examples how the Bakubung people were forced to move to Ledig in present-day North West after initially refusing to move, and the residents of Morajo in Thaba 'Nchu, in present day Free State, who, having approached the Supreme Court for relief, were bluntly told to comply with the removal order.
Desmond warned: 'If we are used to seeing Africans living in hovels in back gardens, cooped up in a location, or being treated like medieval serfs on white farms, then we will not be too horrified when we see them dumped in a veld with a tent and left to fend for themselves.'
By the time apartheid apparatchiks began conceding that their policies were unworkable, more than 3.5-million African people who had been living on the peripheries of rural towns had been forcibly uprooted and moved to the middle of nowhere, there condemned to lives of hopeless poverty.
This was apartheid at its worst. This was how the National Party expropriated land without compensation. This was how they destroyed the lives of rural inhabitants of South Africa.
But it was not only in the rural areas that the government stole property from black people.
Land was stolen in urban areas as well….
I spent my early childhood years in Diep River, a suburb located in the south of Cape Town. We lived in a rented, semi-detached, two-roomed house, in which the roof leaked in winter. But it was located near to the shops, and bus and train transport hubs.
When Group Areas inspectors came to tell the families in the road in which I lived that they would have to move, they asked: "Where would you like to move to? And because everyone had complaints about the houses, and because most people were politically naïve, they chose other suburbs south of the City, such as Plumstead, Wynberg, Claremont, Newlands and Mowbray.
My father, a postman, was entitled to a government housing subsidy. He had a sneaking feeling that a move to Newlands, Claremont, or any of the other places was not going to happen. He decided to investigate the opportunities on the other side of the railway line, in Heathfield.
He heard that a company called Model was building ownership houses there. He took the plunge – for R13 a month over 20 years, thanks to his Post Office subsidy.
And so we moved.
Two of our other close neighbours also moved.
Most of the others stayed – until one day they were given keys and the addresses of their new homes. They were told they would be moving to Manenberg.
I only learnt about the real trauma of that move years later.
We kept in touch with our old neighbours for a while – and we heard lots of stories about those who had moved to Manenberg. They were mostly sad tales. This one's son was now a drug addict. That one was in jail. Those two were killed in a prison gang-fight. And so it went on.
In Cape Town, Group Areas legislation did much more than move people to the sandy wastes of the Cape Flats. It destroyed the lives of men and women who were unable to cope with living in a township. And worse, it set children on the pathway to drugs and gangsterism.
Today, when analysts and so-called experts speak about the danger of the Rand tumbling should the government change the constitution to allow land expropriation without compensation my immediate response is to say, 'Fuck you! You were happy to support apartheid or to say nothing about it. What do you know about being uprooted, about being forcibly removed, about having your family torn apart?'
The very least the Ramaphosa administration should do is base any of their decisions about land on the experiences of those who suffered so grievously at the hands of the administrators and supporters of apartheid.
But will they?

Brenda Rhode says:
You describing your family's lived experience about moving to Heathfield from Newlands,makes this bit of history so personal and authentic..You render the invisible structural violence visible..It clearly shows the relation to visible violence which is on the increase,through crime,delinquency and gang violence and other social ills..
Interesting discourse, Dougie. The landscape of taking property without compensation is a pothole of disasters and could spell disaster for the South African economy for many years. It could usher in a new era of isolation I have not had the good fortune or otherwise of having lived or been evicted from the "leafy suburbs" so my recall is scant. And I have no desirable slice of real estatethat I can remotely seek to claim as my own. But my grandfather, Frik, fought in the Great War. Does that count? I take liberty with your kind permission to offer a different perspective:

Shadley Fataar says:
The term "terra nulius" – "no man's land" comes to mind. Widely known in Australia, it probably had a universal application. No one saw the indigenous conquered people. They were an inconvenience who, at times, had to be removed. Their thousands or hundreds of years of occupation amounted to nought. "Troublemakers" had to be removed or killed off – that was the lot of the vanquished! British "pink" and other European colours covered the world and terra nulius was appled in different ways around the world. My "lest we forget " approach to life is about remembering those past harms to draw the parallels with the present issues. The volstruise remain with their heads in the sand. Your article is forcing them to wiithdraw their heads from past ignorance to shed light on the present. Well done.
Sylvia Vollenhoven says:
Thanks for a piece that touches us because it's personal and honest as well as being journalistically spot on. As you say theft is theft. Reparation is all that makes sense.
Elizabeth Pearce says:
Well done..a little bit of education from the "people of the South" .
The need for re-distribution of land by whatever process grew on me then hit me hard. It's so easy to hide behind our supposed veneers of urban and peri-urban, cosseted lifestyles saying: I'm all right jack!
Notwithstanding existing, and newly published opinion pieces, the text that me hardest was Native Life in South Africa (Sol Plaatje). Both the subject matter and also writing style really nailed it for me.
Mayenzeke!

Can somebody please enlighten me where and when and who the Boers were that just shot blacks at random and"Kidnapped" their children.?
Dougie Oakes says:
Go to Google and search under 'inboekselings'. It'll give you a start.
So it must be tit for tat now and not Democratic? That is what it sounds like., Because many did NOT steal or take land from others and bought theirs on the open market with money they EARNED and PAID INCOME TAX on. Also since 1994 ( That is now nearly for 25 YEARS !) Anybody that had land forcibly taken etc could go and Lodge a Land Claims to get that land back or Compensation.! Many demanding Land have influxed onto land and areas and Cities where they NEVER had any Land to claim in the first place and came from their original homes (which they still have by the way) and LAND to influx to Cities or even other Provinces. What about the land belonging to trusts under the Tribal Chiefs? What about the 2MILLION hectares plus under the Zulu King alone? Also in other Provinces that are all PRIME LAND for farming etc and just lying fallow for decades already? Can you please explain that Mr Oakes as I just cannot seem to understand it all. WHICH land then and where AND WHY WAS IT NOT CLAIMED UNDER THE lAND CLAIMS AS THEIR WAS TIME AND OPPORTUNITY ALREADY SINCE 1994? before the squatters camps already. Is it that now that the Squatters have arrived on land that was never theirs to lay claim to?

Expo Milan 2015
Conceptual Master Plan
> IMAGE |
Expo Milan 2015 adorns itself with a proud title: 'Feeding the Planet, Energy for Life'.
What can architecture and urbanism contribute to a World Exhibition and more specifically: how can the masterplan for a World Exhibition contribute to justify such a proud title? These were the questions we raised when we were asked by the then mayor of Milan, Mrs. Letizia Moratti, to design the masterplan for the Expo Milan 2015. We never liked such big shows, made to attract and impress millions of visitors. We decided to only accept the invitation to design the Milan masterplan if the client would accept a radically new vision for a World Exhibition, abandoning the obsolete idea of expositions solely based on architectural monuments and outmoded vanity shows of national pride that expos have always been since the mid-19th century and that we last experienced in the 2010 Shanghai Expo with its overblown, massive structures. We felt encouraged to go for a radical new approach after learning about Carlo Petrini's involvement. In the early days of the process Carlo gave a very impressive speech about his 'Terra Madre' movement in all parts of this planet. The World Exhibition should bring to the fore all the beauty of this planet's agricultural landscapes, but also all the challenges that come with overpopulation, drought, fertilization/industrialization and patent issues for seeds by multinational agro companies.
In summer 2009 we presented our concept for the masterplan which we developed together with Stefano Boeri, Ricky Burdett and William McDonough to the Bureau International des Expositions. As a reference for our conceptual masterplan we took the cardo/decumanus orthogonal grid system of the antique roman city. We went for this 'timeless' pattern because of its generic openness and its affinity to the 'Ideal City'. Its strong and simple orthogonal geometry would free all participants from any formal architectural exercises and therefore put more focus on the actual contents of the theme 'Feeding the Planted, Energy for Life'. We proposed to encourage all participating countries to abandon the idea of individually designed architectural pavilions and instead accept to present their national agricultural landscapes and gardens in simple and basic pavilion structures provided by the organizers. Such a concept would let all participants contribute in an equally important way alongside a generous boulevard. None of the pavilions would be overwhelming, none would bore us through its idiosyncratic design ambition or divert us from the essential content which is expressed in the message 'Feeding the Planet, Energy for Life'. The large boulevard, literally uniting the pavilions of all participating nations, would become a huge, planetary garden with a long table stretching the full length of the boulevard. This table, inspired by Leonardo's 'Last Supper' would become a place for events, for people to meet and come together, symbolically representing a planetary table for all participants.
The organizers accepted our conceptual plan with its geometric rigor, but we subsequently did not feel supported in approaching and convincing the participating countries to embark on our radical approach for the national pavilions. It was around 2011 when we understood that our hope to re-invent the 21st century World Exhibition would fail and only the geometric pattern of our concept would finally be realized.
