\section{Introduction}
\label{PolyzouWP_intro}

Few-body physics has been transformational in terms of how we
understand low-energy nuclear physics.  The success is largely due to
the existence of uncoupled few-body problems that are directly related
to experiment and cluster properties that relate the few and many-body
Hamiltonians.  Thus, nucleon-nucleon interactions are fine tuned by
comparing cross sections calculated using numerically exact solutions
of the Lippmann-Schwinger equation to experimental nucleon-nucleon
cross sections.  Cluster properties fix how these nucleon-nucleon
interactions appear in N$>$2-body Hamiltonians.  Small corrections due
to three-body interactions can also be fine tuned by comparing
numerically exact solutions of the Faddeev equations with experiment.
Cluster properties again fix how the two and three-body interactions
appear in the N$>$3-body Hamiltonians.  The saturation of nuclear
binding energies suggests that at nuclear densities two, three and
possibly four-body interactions are sufficient to construct
Hamiltonians that provide an accurate description of most nuclei.  The
level of success achieved in low-energy nuclear physics has not been
duplicated for energy scales above the threshold for the production of
pions.

There are a number of reasons for the increased difficulty:

1.) For energies approaching or above the GeV scale the Poincar\'e
group must be a symmetry of the theory so calculations in the
laboratory and center of momentum frame are consistent.  Cluster
properties become more difficult to satisfy in Poincar\'e invariant
models.  While cluster properties can be satisfied for fixed number of
particles\cite{sokolov}\cite{fcwp82}, there is no known systematic
treatment of cluster properties for few-body systems where particle
number is not conserved.

2.) A consistent treatment of particle production also requires a
Poincar\'e symmetric treatment.  Particle production violates Galilean
invariance; momentum conservation cannot be simultaneously satisfied
in two frames related by Galilean boosts.

3.) There is no few-body problem directly related to experiment.  Even
the one-nucleon problem involves an infinite number of bare pions.
This makes it difficult to construct phenomenological few-body
interactions by comparing numerically exact calculations to
experiment.

4.) Even if one can satisfy cluster properties, asymptotically
separated clusters still involve infinite numbers of bare particle
degrees of freedom.

The few-GeV scale is an important energy scale.  It is the scale where
it is possible to study the sensitivity of the dynamics to sub-nucleon
degrees of freedom.  Also, even though the physics involves an
infinite number of bare particle degrees of freedom, we expect that
the dynamics should be dominated by a finite number of suitably chosen
degrees of freedom; it is hard to believe that a small change in
energy would require the number of degrees of freedom needed to
describe nucleon-nucleon scattering to suddenly jump from two to
infinity.

In this talk I discuss a strategy to address all of the difficulties
discussed above, extending the few-body program so it can be used to
make realistic models of systems with invariant energy above the
pion-production threshold that preserve the properties that have made
few-body methods transformational below the pion-production threshold.
The physics motivation for doing this is to extend the success of
few-body methods to energy scales where sub-nucleon degrees of freedom
become relevant.
This is also relevant because it is now possible to solve relativistic
Faddeev equations at the GeV scale \cite{ce1}\cite{ce2}\cite{ce3}.

To treat this problem it is useful to consider the structure of
low-energy few-body models.  In principle, from the point of view of
perturbative field theory, even low-energy nucleon-nucleon scattering
involves an infinite number of bare meson degrees of freedom.
Physical nucleons can also be understood as bare nucleons with a cloud
of virtual mesons.  However, in low-energy nuclear physics one never
deals with the bare nucleon degrees of freedom; instead the relevant
degrees of freedom are taken as physical nucleons.  Their
masses are not calculated, they are measured.  Even though the
structure of the nucleons cannot be calculated, it can still be probed
using scattering experiments.  For example, electron proton-scattering
suggests that the proton has a non-trivial electromagnetic structure.
The fundamental vertex involving bare mesons and nucleons is replaced
by a phenomenological nucleon-nucleon interaction between physical
nucleons.  While the Lippmann-Schwinger equation with realistic
nucleon-nucleon interactions can be solved at all energies, it is only
designed to be taken seriously for energies where the dominant degrees
of freedom are two physical nucleons.  This means that the number of
relevant degrees of freedom is dictated by the energy scale of
interest.  All of this can even be done relativistically using
Poincar\'e symmetric versions of the two-nucleon problem.

The observations in the previous paragraph suggest how to proceed.
Building on the what was successful in the low-energy case, we
formulate the theory using only physical-particle degrees of freedom.
Thus, nucleons, deuterons, and pions will all be taken as physical
particles.  Since physical particles have no-self interactions, a
theory formulated in terms of physical particle degrees of freedom
cannot have elementary vertices, otherwise there would be mass
renormalizations.  Interactions must be short-ranged, involving two or
more initial and two or more final particles.  The simplest
interaction that changes particle number is a short-ranged $2
\leftrightarrow 3$ interaction.  Even if the theory is formulated
using physical particle degrees of freedom, if there is real particle
production, the theory still involves an infinite number of degrees of
freedom.  To have few-body problems directly constrained by experiment
it is necessary to replace a single theory that is applicable at all
energy scales by an ordered sequence of effective theories with
successively more degrees of freedom that are relevant over different
energy scales.  When a system of physical particles is broken up into
asymptotically separated subsystems, the subsystems will involve
lower-energy scales.  Cluster properties can be realized if these
lower energy sub-systems are constrained by the lower-energy effective
theories.

In what follows I use the example of nucleon-nucleon scattering
between the one and two pion-production threshold to illustrate the
structure and construction of such a theory.

\section{Hilbert space}
\label{WP_sec:2}

Minimally, the model Hilbert space must have enough structure so that
it is possible to compute probability amplitudes for any experiment of
interest.  For experiments at a fixed energy scale, it is possible to
measure the momenta and spin projections of every particle that can
appear in an initial or final state.  This motivates the choice of
model Hilbert space as the direct sum of tensor products of single
physical-particle Hilbert spaces, where the particle content
corresponds to the particles that can be experimentally observed at
the given energy scale.  This space has enough degrees of freedom to
describe the results of any experiment that can be performed at the
given energy scale.

Complete experiments on isolated physical particles measure their
mass, linear momentum,  spin, and spin polarization with respect to
some axis in a given frame.  A suitable representation of the
one-particle Hilbert space, ${\cal H}_1$, is the space of square
integrable functions, $\psi (\mathbf{p}, \mu )$, of these observables
\begin{equation}
\psi (\mathbf{p}, \mu ) =
\langle (m,j) \mathbf{p}, \mu
\vert \psi \rangle
\label{a.1}
\end{equation}
\begin{equation}
\langle \psi \vert \psi \rangle =
\int
\sum_{\mu=-j}^j\vert \psi (\mathbf{p}, \mu ) \vert^2 d\mathbf{p} <
\infty
\label{a.2}
\end{equation}
where $(m,j)$ are the physical mass and spin of the particle.

The formulation of cluster properties works best when the theory is
formulated in terms of tensor products.  In order to preserve the
tensor product structure in models with particle production, it is
useful to replace the single particle Hilbert space by the direct sum
of a single particle Hilbert space and a zero dimensional no-particle
space:
\begin{equation}
{\cal H}_1 \to {\cal H}_1 \oplus \{0 \} .
\label{a.3}
\end{equation}
These doublet spaces were first introduced by Sokolov\cite{sokolov}.
The tensor product of doublet spaces can be decomposed as a direct sum of
tensor products.  For example, if the
system has particles of type $b$,$c$,and $d$, the tensor product of
the three doublet spaces can be expanded into a direct sum of
subspaces with all particle contents involving particles $b$,
$c$, and $d$.
\[
({\cal H}_b\oplus \{0\}) \otimes
({\cal H}_c\oplus \{0\}) \otimes
({\cal H}_d\oplus \{0\})
 =
\]
\[
({\cal H}_b \otimes
{\cal H}_c \otimes
{\cal H}_d ) \oplus
({\cal H}_b \otimes
{\cal H}_c )
\oplus
({\cal H}_c \otimes
{\cal H}_d )
\oplus
\]
\begin{equation}
({\cal H}_d \otimes
{\cal H}_b )
\oplus
{\cal H}_b\oplus
{\cal H}_c\oplus
{\cal H}_d\oplus \{0\} .
\label{a.4}
\end{equation}
In specific models some of these combinations do not appear because of
super-selection rules, energy considerations, or properties of the
interactions.  In what follows, we construct our models
assuming that the particles are initially distinguishible, and then
treat the particle identity when computing the cross sections.

The single-particle spaces are also irreducible representation spaces
for the Poincar\'e group.  The unitary irreducible representation,
$U_1(\Lambda ,a)$, of the Poincar\'e group on the single particle
Hilbert space ${\cal H}_1$ is
\[
\langle (m,j) \mathbf{p}, \mu \vert U_1(\Lambda ,a)
\vert \psi \rangle =
\]
\[
\int  \sum_{\mu'=-j}^j
\langle (m,j) \mathbf{p}, \mu \vert U_1(\Lambda ,a)
\vert (m,j) \mathbf{p}', \mu' \rangle d\mathbf{p}'
\times
\]
\[
\langle (m,j) \mathbf{p}', \mu'
\vert \psi \rangle =
\]
\begin{equation}
\int  \sum_{\mu'=-j}^j
{\cal D}^{mj}_{\mathbf{p}, \mu; \mathbf{p}', \mu'}
[\Lambda ,a] d\mathbf{p}' \psi (\mathbf{p}', \mu' )
\label{a.5}
\end{equation}
where the Poincar\'e group Wigner function is
\[
{\cal D}^{mj}_{\mathbf{p}, \mu; \mathbf{p}', \mu'}
[\Lambda ,a] :=
\langle (m,j) \mathbf{p}, \mu \vert U_1(\Lambda ,a)
\vert (m,j) \mathbf{p}', \mu' \rangle =
\]
\begin{equation}
e^{i p \cdot a}
\sqrt{{\omega_m (\mathbf{p}) \over \omega_m (\mathbf{p}') }}
\delta (\mathbf{p} - \mbox{\boldmath$\Lambda$} p' )
D^i_{\mu \mu'}[B^{-1} (p/m)\Lambda B(p',m) ]
\label{a.6}
\end{equation}
with
\begin{equation}
\omega_m (\mathbf{p}) = \sqrt{\mathbf{p}^2 + m^2}
\label{a.7}
\end{equation}
and $B(p/m)$ is a Lorentz boost
\begin{equation}
B(p/m) (m,0,0,0) = p
\label{a.8}
\end{equation}
that depends on the choice of spin polarization observable (helicity,
canonical spin, null-plane spin).  The quantity
$B^{-1} (p/m)\Lambda B(p'/m)$
is a Wigner rotation.

The direct sum of tensor products of these single-particle
unitary irreducible representations, where the representation acts
like the identity on the zero dimensional no-particle state,
defines the non-interacting representation, $U_0(\Lambda,a)$, of
the Poincar\'e group
on the model Hilbert space.  On the tensor product of the three
doublet spaces (\ref{a.4}) it has the form
\[
U_0(\Lambda ,a) =
[U_a(\Lambda ,a) \otimes
U_b(\Lambda ,a) \otimes
U_c(\Lambda ,a) ] \oplus
\]
\[
[U_a(\Lambda ,a) \otimes
U_b(\Lambda ,a) ] \oplus
[U_b(\Lambda ,a) \otimes
U_c(\Lambda ,a) ] \oplus
\]
\[
[U_c(\Lambda ,a) \otimes
U_a(\Lambda ,a) ] \oplus
U_a(\Lambda ,a) \oplus
\]
\begin{equation}
U_b(\Lambda ,a) \oplus
U_c(\Lambda ,a)  \oplus I .
\label{a.9}
\end{equation}

\section{Nucleon-nucleon scattering model}
\label{WP_sec:3}

Consider nucleon-nucleon scattering for invariant energy between
$2m_N + m_\pi$ and $2m_N + 2m_\pi$.  In this energy range
the possible baryon number two states are
$(NN)$, $(NN\pi)$, $(D\pi)$, $(D\pi\pi)$ .
Using Sokolov's doublet formalism and treating the nucleons and
pions as distinguishible, the model Hilbert space is the
following direct sum of
tensor products of two and three particle spaces:
\[
{\cal H} = {\cal H}_{N_1N_2} \oplus
{\cal H}_{N_1N_2\pi_1} \oplus
{\cal H}_{N_1N_2\pi_2} \oplus
\]
\begin{equation}
{\cal H}_{D\pi_1} \oplus
{\cal H}_{D\pi_2} \oplus
{\cal H}_{D\pi_1\pi_2}.
\label{a.10}
\end{equation}
Vectors in this space are represented by six-component wave functions:
\begin{equation}
\Psi (\cdots )=
\left (
\begin{array}{c}
\psi_{NN} (\mathbf{p}_N,\mu_N,\mathbf{p}_{N'},\mu_{N'} )\\
\psi_{D\pi} (\mathbf{p}_D,\mu_D,\mathbf{p}_{\pi}  )\\
\psi_{D\pi'} (\mathbf{p}_D,\mu_D,\mathbf{p}_{\pi'}  )\\
\psi_{NN\pi} (\mathbf{p}_N,\mu_N,\mathbf{p}_{N'},\mu_{N'},\mathbf{p}_{\pi}  )\\
\psi_{NN\pi'} (\mathbf{p}_N,\mu_N,\mathbf{p}_{N'},\mu_{N'},\mathbf{p}_{\pi'}  )\\
\psi_{D\pi\pi} (\mathbf{p}_D,\mu_P,\mathbf{p}_{\pi},\mathbf{p}_{\pi'})\\
\end{array}
\right ) .
\label{a.11}
\end{equation}

The kinematic unitary representation of the Poincar\'e group is
\[
U_0(\Lambda ,a) =
[U_{N}(\Lambda ,a) \otimes U_{N'}(\Lambda ,a)]\oplus
[U_{D}(\Lambda ,a) \otimes U_{\pi}(\Lambda ,a)]\oplus
\]
\[
[U_{D}(\Lambda ,a) \otimes U_{\pi'}(\Lambda ,a)]\otimes
[U_{N}(\Lambda ,a) \otimes U_{N'}(\Lambda ,a)\otimes U_{\pi}(\Lambda ,a)]\oplus
\]
\[
[U_{N}(\Lambda ,a) \otimes U_{N'}(\Lambda ,a)\otimes U_{\pi'}(\Lambda ,a)]\oplus
\]
\begin{equation}
[U_{D}(\Lambda ,a) \otimes U_{\pi}(\Lambda ,a)\otimes U_{\pi'}(\Lambda ,a)].
\label{a.11b}
\end{equation}

\section{Dynamics}
\label{WP_sec:4}

In a quantum mechanical model a Poincar\'e symmetry is implemented
by a unitary representation of the Poincar\'e group\cite{wigner}.
The representation is necessarily dynamical\cite{dirac}.

The free-particle representation, $U_0(\Lambda, a)$, is reducible on
the model Hilbert space ${\cal H}$.  Poincar\'e group Clebsch-Gordan
coefficients \cite{moussa}\cite{coester}\cite{bkwp} can be used to
decompose the Hilbert space into a direct integral of invariant
subspaces on which $U_0(\Lambda,a)$ acts irreducibly.
The
Clebsch-Gordan coefficients have the form
\[
\langle (12)\vert 3 \rangle =
\]
\begin{equation}
\langle (m_1,j_1)\mathbf{p}_1, \mu_1 (m_1,j_2)\mathbf{p}_2, \mu_2
\vert (\mathbf{k}^2 , j_3 ) \mathbf{p}_3, \mu_3, d \rangle
\label{a.12}
\end{equation}
where $\mathbf{k}^2$ is a more convenient label for the
invariant mass $m_3$ of the combined system
\begin{equation}
m_3 = \sqrt{m_1^2 + \mathbf{k}^2} + \sqrt{m_2^2 + \mathbf{k}^2} .
\end{equation}
In what follows we use $m_3$ and $\mathbf{k}^2=k^2$ interchangeably.
Multiple copies of invariant subspaces with the same mass and spin
are separated by invariant degeneracy parameters $d$.
The parameters $d$ are related
to the squares of spin $s^2$ and orbital angular momentum $l^2$ of the
$12$-pair.
Three particle irreducible representations can be constructed by
successive pairwise coupling.

The irreducible basis states are labeled by the same
quantities that are used to label the single-particle states; linear momentum,
mass, spin, spin projection, as well as a number of Poincar\'e
invariant degeneracy parameters which we label by $d_n$, where
$n \in \{ NN$,$NN\pi$,$NN\pi'$,$D\pi$,$D\pi'$,$D\pi\pi \}$ .
These eigenstates are complete on the model Hilbert space.  A basis of
non-interacting Poincar\'e irreducible states consists of the
generalized vectors
\begin{equation}
\vert (m,j)\mathbf{p},\mu, d_n,n \rangle  =
\left (
\begin{array}{c}
0 \\
\vdots \\
\vert (m,j) \mathbf{p},\mu, d_n \rangle \\
\vdots \\
0 \\
\end{array}
\right ) .
\label{a.12a}
\end{equation}
The non-interacting invariant mass operator, $M_0$, is the mass
Casimir operator of $U_0(\Lambda,a)$.  It
has a continuous spectrum
and is a multiplication operator in the representation (\ref{a.12a}).
Interactions of the form \cite{bakamjian}:
\[
\langle (m',j')\mathbf{p}',\mu', d_{n'}',n' \vert V
\vert (m,j)\mathbf{p},\mu, d_{n},n \rangle
=
\]
\begin{equation}
\delta (\mathbf{p}'-\mathbf{p})\delta_{j'j}\delta_{\mu'\mu}
\langle  m', d_{n'}',n' \Vert V^j
\Vert m, d_n,n \rangle
\label{a.13}
\end{equation}
are added to the non-interacting mass operator, $M_0$,  to construct a
dynamical mass operator:
\begin{equation}
M= M_0+V .
\label{a.14}
\end{equation}
Simultaneous eigenstates $\vert (\lambda,j) \mathbf{p}, \mu , d
\rangle$
of $M,j,\mathbf{p},\mu$ are complete.  The dynamical problem is to
solve the eigenvalue problem
\begin{equation}
(M_0+V) \vert (\lambda,j) \mathbf{p}, \mu , d \rangle =
\lambda \vert (\lambda,j) \mathbf{p}, \mu , d \rangle
\label{a.14a}
\end{equation}
in the non-interacting irreducible basis.  The eigenfunctions in the
non-interacting irreducible representation can be expressed in terms
of wave functions $\Psi_{\lambda,j,d} (m',d_{n'}', n')$:
\[
\langle (m',j') \mathbf{p}', \mu' ,d_{n'}',n' \vert (\lambda,j)
\mathbf{p}, \mu , d \rangle =
\]
\begin{equation}
\delta (\mathbf{p}'-\mathbf{p})\delta_{j'j}\delta_{\mu' \mu}
\Psi_{\lambda,j,d} (m',d_{n'}', n').
\label{a.15}
\end{equation}
There is a natural dynamical unitary representation of the Poincar\'e
group defined on these eigenstates by
\[
\langle (m',j') \mathbf{p}', \mu' ,d_{n'}',n'  \vert U(\Lambda ,a)
\vert  (\lambda,j) \mathbf{p}, \mu , d
\rangle =
\]
\begin{equation}
\Psi_{\lambda,j,d} (m',d_{n'}' n')
{\cal D}^{\lambda j}_{\mathbf{p}, \mu; \mathbf{p}', \mu'} [\Lambda ,a]
\label{a.16}
\end{equation}
where $\lambda$ the eigenvalue of $M$.  Completeness of the
eigenstates ensures that this representation is defined on any state.
The dynamics enters through the appearance of the mass eigenvalue,
$\lambda$, in the Poincar\'e group Wigner function ${\cal D}^{\lambda
  j}_{\mathbf{p}, \mu; \mathbf{p}', \mu'} [\Lambda ,a]$.

This construction can be done for any finite number of degree of
freedom system.  What is relevant in this construction is that the
spin $j$ in the dynamical model is the same as the spin $j$ in the
non-interacting model.  We refer to this construction of dynamical
representation of the Poincar\'e group as the generalized
Bakamjian-Thomas\cite{bakamjian} construction.

Three different two-body models are needed as input to the
full dynamical model.  These two-body models are a $\pi-N$  model,
a $\pi-\pi$ model and a coupled channel $NN\leftrightarrow D\pi$
model.  In what follows we replace the invariant mass $m_3$ by the
relative momentum variable $k=\sqrt{\mathbf{k}^2}$.  For the coupled channel model
the non-interacting invariant mass operator has the form
\begin{equation}
M_0 :=
\left (
\begin{array}{cc}
2\sqrt{{k}_{NN}^2+m_N^2}& 0 \\
0 & \sqrt{{k}_{D\pi}^2+m_D^2} +\sqrt{{k}_{D\pi}^2+m_\pi^2}
\end{array}
\right ).
\label{b.1}
\end{equation}
The interaction $V$ is defined by the kernel in the irreducible two-body
variables
\[
\delta (\mathbf{p}'-\mathbf{p})
\delta_{j'j}\delta_{\mu' \mu} \times
\]
\begin{equation}
\left (
\begin{array}{cc}
\langle k_{nn}', l', s' \vert v_{NN;NN}^j \vert k_{nn}, l, s \rangle &
\langle k_{nn}', l', s' \vert v_{NN;D\pi}^j \vert k_{D\pi}, l, 1 \rangle \\
\langle k_{D\pi}', l', 1 \vert v_{D\pi;NN}^j \vert k_{nn}, l, s \rangle &
\langle k_{D\pi}', l', 1 \vert v_{D\pi;D\pi}^j \vert k_{D\pi}, l, 1 \rangle
\end{array}
\right ) .
\label{b.2}
\end{equation}
The dynamical mass operator on
${\cal H}_{NN} \oplus {\cal H}_{D\pi}$ is $M=M_0+V$, where
$V$ is the interaction defined by the kernel (\ref{b.2}).
Simultaneous eigenstate of $M$, $j$, $\mathbf{p}$, and
$\hat{\mathbf{z}} \cdot \mathbf{j}$ from a complete set of basis
vectors that transform irreducibly with respect to a dynamical
representation $U_{NN-D\pi} (\Lambda ,a) $
\[
\langle (\lambda',j') \mathbf{p}', \mu',d' \vert U_{NN-D\pi} (\Lambda ,a)
\vert (\lambda,j) \mathbf{p}, \mu,d \rangle =
\]
\begin{equation}
\delta_{j'j} \delta (\lambda' -\lambda) \delta_{d'd}
{\cal D}^{\lambda j}_{\mathbf{p}, \mu; \mathbf{p}', \mu'}
[\Lambda ,a]
\label{b.3}
\end{equation}
where $\lambda$ is the eigenvalue of the dynamical mass operator $M$.
A similar construction can be done for the $\pi-\pi$ and $\pi-N$ systems,
resulting in the representations $U_{NN-\pi D} (\Lambda ,a)$ on ${\cal
  H}_{NN} \oplus {\cal H}_{D\pi}$, $U_{N-\pi} (\Lambda ,a)$ on ${\cal
  H}_{N\pi}$ and $U_{\pi\pi} (\Lambda ,a)$ on ${\cal H}_{\pi\pi}$.
These models are only required to fit scattering below the
pion-production threshold.  Because the bound states are treated as
physical degrees of freedom, the spectrum of the mass operator in
these two-body models is continuous.

\section{Algebraic cluster properties}
\label{WP_sec:5}

Cluster properties dictate how two-body interaction are embedded in
the three-body sectors of the model Hilbert space.  Cluster properties
are normally implemented by translations.  In this framework
translations used to separate subsystems only operate on subspaces of
the Hilbert space were the translations make sense; for example it
makes no sense to separate nucleons on a subspace containing the
deuteron.  Translations that asymptotically separate subsystems ensure
that the short-ranged interactions between particles in separated
clusters vanish, however the difficulty in Poincar\'e invariant quantum
mechanics is that the translations can cause interactions that should
not vanish to vanish in the cluster limit.  This {\it will not happen
  if result of simply turning-off interactions results in a tensor
  product of subsystem unitary representations} of the Poincar\'e
group.  We call this type of clustering algebraic clustering
and use it in what follows.

Consider the problem of nucleon-nucleon scattering for invariant
energies between the one and two pion-production threshold.  The model
Hilbert has six orthogonal sectors with different particle contents.
There are three three-body sectors, each having at least one pion.  If
we translate one of the particles away from an interacting pair in one
of the three-body sectors, then the invariant energy remaining for the
interacting pair is insufficient to produce another pion.  Algebraic
cluster properties requires that in this limit the Poincar\'e
generators in this sector should become the sum of one-body
generators corresponding to the spectator particle and dynamical
two-body generators associated with an interacting two-body systems
having insufficient invariant energy to create an additional pion.
This is equivalent to the dynamical unitary representation of the
Poincar\'e group becoming a tensor product.
In
each of these sectors there are three different two-body interactions
that arise from cluster properties, depending on which particle is
asymptotically separated.

These are the only constraints that cluster properties place on this
model.  The two-body sectors are relevant for invariant energies
above the threshold for the production of a pion and in principle do not
have to be related to the lower-energy two-body Hamiltonians.

The problem of two interacting particles and a spectator can be
solved using two different methods.  The first one is to construct the
two-body unitary representation of the Poincar\'e group,
$U_{NN - D\pi}(\Lambda,a)$, $U_{N\pi}(\Lambda,a)$,
$U_{\pi\pi'}(\Lambda,a)$ and then take the tensor product with the
spectator representation
\begin{equation}
U_{NN - D\pi}(\Lambda,a)\otimes U_{\pi'}(\Lambda,a), \,
\label{b.4}
\end{equation}
\begin{equation}
U_{N\pi}(\Lambda,a)\otimes U_{N'}(\Lambda,a), \,
\label{b.5}
\end{equation}
\begin{equation}
U_{\pi\pi'}(\Lambda,a)\otimes U_{D}(\Lambda,a) .
\label{b.6}
\end{equation}
The second method uses the standard construction where we first use
Poincar\'e Clebsch Gordan coefficients to decompose the non-interacting
three-body representations into a direct integral of non-interacting irreducible
representations.  Interactions of the from (\ref{a.13}) are added to the
non-interacting mass, which is then diagonalized to construct $U(\Lambda,a)$.
We refer to these two representations as the tensor product representation
and the Bakamjian-Thomas representation respectively.
I denote the Bakamjian-Thomas representations by
\begin{equation}
U_{NN - D\pi;\pi'}(\Lambda,a),
\label{b.7}
\end{equation}
\begin{equation}
U_{N\pi;N'}(\Lambda,a),
\label{b.8}
\end{equation}
\begin{equation}
U_{\pi\pi';D}(\Lambda,a)  .
\label{b.9}
\end{equation}
These operators do not act on the full Hilbert space.  They act on a
subspace of the full Hilbert space.  They can be extended to operators
on the full Hilbert space by extending them to be the identity on the
orthogonal complement of the subspace.

The kernel of the two-body interaction in the two-body kinematic irreducible
representation (\ref{a.13}) depends on the kinematic two-body relative
momentum and kinematically-invariant two-body degeneracy parameters.
By coupling irreducible representations in the appropriate order, the
same variables also appear in the three-body kinematic irreducible basis.  Using
the same kernel, with different delta functions, it is easy to show
that the tensor product and Bakamjian-Thomas representations of the
dynamics of two interacting particles and a spectator give the same
$2+1$ S-matrix.  This follows because the delta functions that
multiply the interaction also appear in the $S$-matrix, and they
become equivalent when the $S$-matrix is evaluated on-shell.  While
the $2+1$ unitary representations of the Poincar\'e group are
not-equivalent, a theorem of Ekstein \cite{ekstein} implies that each
representation is related by a unitary transformation, $W$, that also
preserves the $S$ matrix.

Thus these two representations are related by
\[
W_{NN-D\pi;\pi'}  U_{NN-D\pi;\pi'} (\Lambda,a)
W^{\dagger}_{NN-D\pi;\pi'} =
\]
\begin{equation}
U_{NN-D\pi} (\Lambda,a) \otimes U_{\pi'} (\lambda ,a)
\end{equation}
\begin{equation}
W_{N\pi;N'}  U_{N\pi;N'} (\Lambda,a)
W^{\dagger}_{N\pi;N'} = U_{N\pi} (\Lambda,a) \otimes U_{N'} (\Lambda ,a)
\end{equation}
\begin{equation}
W_{\pi\pi';D}  U_{\pi\pi';D} (\Lambda,a)
W^{\dagger}_{\pi\pi';D} = U_{\pi \pi'} (\Lambda,a) \otimes U_{D} (\Lambda ,a).
\end{equation}
Because the interactions in the Bakamjian-Thomas representation
commute with the kinematic spin, they can be combined with the
remaining short-ranged interactions in a manner
that leads to an overall interaction of the form (\ref{a.13}).
The Bakamjian Thomas construction then be used to construct a
dynamical representation of the Poincar\'e group on the model
Hilbert space.

The unitary operators $W_x$ operate on a subspace of the Hilbert space.
They can be extended to unitary operators on ${\cal H}$ by setting
them equal to the identity on the orthogonal complement of the
space on which they are defined.

\section{Construction of the dynamical mass operator}
\label{WP_sec:6}

The dynamical mass operator for our model in the Bakamjian-Thomas
representation has three distinct types of contributions

The first is the mass operator $M_0$ for the non-interacting system
{\footnotesize
\begin{equation}
M_0 = \left (
\begin{array}{cccccc}
M_{0NN'} &0&0&0&0&0\\
0 & M_{0D\pi} &0&0&0&0\\
0 & 0 & M_{0D\pi'} &0&0&0\\
0 & 0 & 0 & M_{0NN'\pi}&0&0 \\
0 & 0 & 0 & 0 & M_{0NN'\pi'}&0 \\
0 & 0 & 0 & 0 & 0 & M_{0D\pi\pi'}
\end{array}
\right )
\label{a.18}
\end{equation}
}
where the non-zero entries in this matrix are the invariant masses
of the systems of particles on each subspace.  This is the limiting
form of this mass operator when all interactions are switched off.

Next we add lower-energy two-body interactions in each of the
three-particle sectors:
{\footnotesize
\begin{equation}
V_2=
\left (
\begin{array}{cccccc}
0&0&0&0&0&0\\
0&0&0&0&0&0\\
0&0&0&0&0&0\\
0 & 0 & 0 &v_{NN'} + v_{N\pi} + v_{N'\pi} & 0 & v_{NN;\pi D} \\
0 & 0 & 0 & 0 & v_{NN'} + v_{N\pi'} + v_{N'\pi'} & v_{NN;\pi' D} \\
0 & 0 & 0 & v_{NN;\pi D}^{\dagger} & v^{\dagger}_{NN;\pi' D} & v_{D\pi} + v_{D\pi'} + v_{\pi\pi'}
\end{array}
\right ).
\label{a.19}
\end{equation}
}

These are the interactions that come from the two-body
Bakamjian-Thomas representations.  They are related to the
tensor product representations by the unitary transformations
$W$.  For example:
{\footnotesize
\[
\left (
\begin{array}{cccccc}
0&0&0&0&0&0\\
0&0&0&0&0&0\\
0&0&0&0&0&0\\
0 & 0 & 0 &v_{NN'} & 0 & v_{NN;\pi D} \\
0 & 0 & 0 & 0 & 0 & 0 \\
0 & 0 & 0 & v_{NN;\pi D}^{\dagger} & 0 & v_{D\pi}
\end{array}
\right ) =
\]
}
{\footnotesize
\[
W^{\dagger}_{NN\leftrightarrow D\pi'}
\left (
\begin{array}{cccccc}
0&0&0&0&0&0\\
0&0&0&0&0&0\\
0&0&0&0&0&0\\
0 & 0 & 0 &m_{NN'\otimes \pi} & 0 & m_{NN;\pi' D\otimes \pi} \\
0 & 0 & 0 & 0 & 0 & 0 \\
0 & 0 & 0 & m_{NN;\pi' D\otimes \pi}^{\dagger} & 0 & m_{D\pi';\otimes \pi}
\end{array}
\right )
W^{\dagger}_{NN\leftrightarrow D\pi'}  -
\]
}
{\footnotesize
\begin{equation}
\left (
\begin{array}{cccccc}
0&0&0&0&0&0\\
0&0&0&0&0&0\\
0&0&0&0&0&0\\
0 & 0 & 0 &m_{0NN' \pi} & 0 & 0 \\
0 & 0 & 0 & 0 & 0 & 0 \\
0 & 0 & 0 & 0 & 0 & m_{0D\pi'\pi}
\end{array}
\right ).
\label{a.20}
\end{equation}
}
The third class of operators, $V_3$ are fully connected operators.
These are two-body interactions in the two-body sectors, three-body
interactions in the three-body sectors, $2-2$ interactions coupling
different two-body sectors and $2-3$-body interactions coupling two
and three-body sectors.  All of the two-body interactions
in $V_3$ describe
physics above the pion-production threshold and thus do not have to be
related to the interactions below the pion-production threshold.  In
addition to being connected, all of these interactions must have
kernels of the form (\ref{a.13}) in the non-interacting Poincar\'e
irreducible representation.  These connected operators do not
contribute to the cluster limit associated with lower energy
subsystems.

In this way the operator $M_{BT} = M_0 + V_2 + V_3$ commutes with
$j$ and commutes with and is independent of $\mathbf{p}$ and $
\mathbf{j}\cdot \hat{\mathbf{z}}$.  Simultaneous eigenstates of these
operators are complete and transform irreducibly as mass $\lambda =$ eigenvalue
of $M_{BT}$, spin $j$, irreducible representations of the Poincar\'e group.
We denote the resulting unitary representation of the Poincar\'e group by
$U_{BT} (\Lambda ,a)$.  When interactions between cluster $b$ and $c$
in one of the three-body sectors are turned off, $U_{BT} (\Lambda ,a)$
fails to break up into a tensor product.  Instead it becomes:
\begin{equation}
U_{BT} (\Lambda ,a) \to W_{bc} [ (U_{b}(\Lambda ,a) \otimes
U_{c}(\Lambda ,a))\oplus \cdots ] W^{\dagger}_{bc}
\end{equation}

This can be repaired defining a symmetric product of the
$W$ operators
\begin{equation}
W := e^{\sum \ln W_a}
\end{equation}
where the sum runs over
\[
a \in \{ [(NN-D\pi); \pi'],
[(NN-D\pi'); \pi],  (\pi \pi';D),(D\pi; \pi'),
\]
\begin{equation}
(D\pi';\pi),
(N\pi;N'),(N'\pi;N),(N\pi';N'),(N'\pi';N)\}.
\end{equation}
This operator is designed so
\[
U (\Lambda ,a):=
\]
\begin{equation}
W^{\dagger} U_{BT} (\Lambda ,a)W
\to  [ (U_{b}(\Lambda ,a) \otimes
U_{c}(\Lambda ,a))\oplus \cdots ]
\end{equation}
when the interactions between particles in cluster $b$ and $c$
are turned off.  This shows that it satisfies algebraic cluster
properties.  Because $W$ is unitary,
$U (\Lambda ,a):= W^{\dagger} U_{BT} (\Lambda ,a)W$,  is also a dynamical
representation of the Poincar\'e group.

The completes the construction of the dynamics for the two-nucleon system
of energies between the one and two-pion production threshold.
Thus we have a two-particle model that describes nucleon-nucleon
scattering below the one-pion-production threshold, and we have a second model
that described nucleon-nucleon scattering for invariant energies between the one
and two-pion-production thresholds.
While the models are uncoupled,  interactions from the lower energy
two-body model
appear in the three-body sector of the higher-energy model.
Both models are exactly Poincar\'e invariant with interactions that
can be directly constrained by few-body experiments.

This general construction can be repeated inductively at higher energy
scales.  By using the doublets the entire inductive construction used
in the fixed number of particle case \cite{fcwp82} can be generalized
to this setting.

\section{Outlook}

This work demonstrates that it is possible to overcome all of the
difficulties in needed to extend the successful low-energy few-body
program to higher energy scales.  In this formalism the independent
degrees of freedom are taken as physical particles.  This also applies
to bound states.  This is not a problem in principle, but it does mean
that much of the work done in constructing realistic few-body
interactions needs to be repeated in this setting.  Another new
feature is that the many-body interactions of the non-relativistic
theory are replaced by both many-body interactions and hard
(high-energy) two-body interactions.  At each successive energy scale
it is necessary to introduce new hard two-body interactions.  In most
cases these interactions appear in the entrance channel and thus
cannot be ignored.  An independent method for constructing these hard
interaction would prove to be very useful in this framework.  Still, a
good part of the high-energy dynamics is strongly constrained by the
few-body dynamics through cluster properties.

This work was performed in part under the auspices of the

Developing Minimally Invasive Surgery Centers Within Kaiser Permanente: The Integrated Multidisciplinary Experience of Los Angeles
Gary W Chien, MD; Maher A Abbas, MD, FACS, FASCRS
Spring 2009 - Volume 13 Number 2
https://doi.org/10.7812/TPP/08-104
Minimally invasive surgical therapies are growing in type and volume of interventions. As one of the largest health delivery organizations in the US, Kaiser Permanente staff must be aware that the proliferation of these technologies has occurred in parallel within many surgical specialties, with a large variation in level of implementation between different regions and even within regions. In Los Angeles, we have developed the Minimally Invasive Surgery Center, encompassing a multidisciplinary, integrated approach. It unites the effort and expertise of many outstanding practitioners within the organization and consolidates the achievements of many surgical specialties. It also brings together the elements needed to provide the highest level of care to our patients in a safe, efficient, cost-effective environment, with minimal morbidity and best long-term outcome.

Italy Pay The Penalty As All-Whites Hold Out For A Draw
Jamie Shaw
World Champions Italy struggled to a 1-1 draw against minnow opposition New Zealand in Nelspruit on Sunday, leaving their chances of reaching the last 16 hanging in the balance.
Once again the Azzurri were slow out of the traps and after just six minutes, New Zealand were in front. A free-kick was swung into the box and found its way to Smeltz at the far post, who duely converted the ball past the stand-in keeper Federico Marchetti; the goal standing despite the striker seemingly being a yard offside.
This however proved to be a wake up call for the Italians, who soon trapped New Zealand inside their own half, creating numerous chances but failing to take advantage. The most noteable chance fell to Ricardo Montolivo on 27 minutes, his long range drive striking the foot of the right-hand post. The New Zealand resistance was finally broken moments later when defender Tommy Smith brought down Daniele De Rossi inside the area; De Rossi's dramatic reaction no doubt swaying the referee to award a much needed penalty for Italy. In form striker Vincenzo Iaquinta cooly dispatched the spot kick, sending the goalkeeper the wrong way to restore parity as well as relief going into the break.
A second goal looked on the cards for the favourites as they continued to huff and puff in the second half, but it was not to be, despite Lippi's best attempt to grind out three points, throwing on both Di Natale and Camoranesi. Iaquinta's late last ditch effort was heroicly blocked by the All-Whites' Winston Reid and moments later their prayers for the sound of the final whistle were answered.
Although the game was dominated by Italy in the attacking third, a point seemed a fair reward for New Zealand's determined defending. Italy need Pirlo back as soon as possible. "We hope he will be back for the Slovakia game, but we cannot be 100% certain," manager Marcello Lippi said. "We have to win that game now, there is no other way around it, because we do not want to go home." Italy's third and final group games sees them travel to Ellis Park on Thursday in a crucial win or bust game against contenders Slovakia.

In the orthodox teaching we say that some belong to the state of the slave, others to the state of the hireling and others to the state of the son. In general, it must be pointed out that sin in the orthodox teaching is darkening of the nous, while repentance and forgiveness of sins are the illumination of the nous. Sin is regarded as an illness of the soul. Sin is not placed in a legal framework, but a medical one.
In conclusion we can say that our relationship with God should not be regarded as juridical, legal, but as personal ecclesiastical. The legalistic view is alien to the orthodox mind. When we think that God has been offended by the sin which we commit and that we must therefore do everything to appease Him, when our relationship with God is put on a business basis, then we are living in the legalistic spirit.
His "take" is–understandably–consistent with BOTH the piece you sent earlier (with which I am intermittently "wrestling", but not like Jacob); and with our contemporary secular world view that sin is a "medical" condition, treatable not with theology but with therapy. See: TRIUMPH OF THE THERAPEUTIC by Phillip Rieff.
Hi Derek. I don't believe the orthodox view would deny that God can, does and will punish sin but rather sees this discipline within a greater context of healing for our salvation. Further it sees theology, or the communion of man with God through Christ, as the definition of healing.
Thanks Derek. The Orthodox certainly wouldn't do away with the concept of sin or pass the buck regarding our responsibility for our sin. I think the orthodox view would hold sin and discipline within a greater context of healing though. Correction of sin to heal the sinner as an aspect of his salvation in the Lord. I will check into that book but from what you wrote it sounds like it describes a very different meaning of spiritual therapy than the orthodox meaning.

At MiQ we're big sports fans – and even bigger fans of advertising data and analysis. While this year's Super Bowl wasn't the most exciting game we've ever watched, there was a ton of data to look through around how people watched this year and how they responded to the most expensive commercials ever shown. Let's dive into the data and look at how America handled this year's Big Game.
This data comes from a mixture of sources. Primarily MiQ's log-level integration with AppNexus, which provides impression data and TV usage data from opted-in Vizio and LG smart TVs. This data comes from January and February, 2021.
How Americans ate during the Super Bowl
Having a spread of great food for Super Bowl Sunday is a time-honored tradition and, with the pandemic making attending bars and restaurants less likely, this year was no exception. Take-out and delivery orders increased all week leading into the day of the game.
Americans stayed home this year
Prior to the game, the CDC expressed concern over Super Bowl parties being 'super-spreader' events. While that may still end up being the case, food orders seem to indicate that people generally stayed home during the game – order sizes on game day were about the same as they had been all week, though people were generally more likely to order in. Four out of ten Americans who put an order item in their cart ended up making a purchase, up 23% from last week.
Viewers were more likely to cook this year
Traffic on cooking websites increased 37% leading into the Super Bowl this year, suggesting that people were more interested in home-cooked spreads than delivery.
Drink delivery services were the big winners
Activity on grocery websites and alcohol/drink delivery sites increased 72% over last year's game day as people turned to safer means of drink acquisition. 92% of these orders came from repeat customers (who had made an order in the three months prior).
Watching the Super Bowl… and something else
Using our sample of opted-in Smart TVs, we identified 2.3m US households who tuned into the live telecast, and of those about half watched for more than three hours. 16% of TV viewers tuned in through OTT platforms or apps. Spanish language viewers accounted for about 12% of viewership and 94% of those viewers watched the entire game.
Phone usage during the Super Bowl
We counted 17.6m internet-connected devices in those 2.3m households. 56% of the active devices during the game were phones that generated a median of nine impressions during the game, though some generated as many as 300. While overall the number of active second screens during the game decreased by 7%, the people who were on their phones during the game were much more active – the amount of activity per device, as well as the number of ad opportunities generated, went up 4%.
If someone was going online while watching the Super Bowl, news and sports were the most likely content categories they'd be looking at, accounting for 22% and 18%, respectively, of pages viewed on second screens during the game. Online gaming also went up 69% on mobile devices that were active while watching the game. Consumers' response rate to ads remained about the same.
Watching Super Bowl ads
The average viewer saw 50 commercials during this year's game, and those watching the entire thing could have seen 80 or more. 92% of the game's ads were shown to completion. The impact of that exposure was mixed. Looking at search data from the game shows that there was a measurable but small positive correlation between this year's TV ads and search activity for those brands (r=0.231), though the big winners here were food and drink brands. Doritos, Cheetos, Lays, Anheuser-Busch, Uber Eats, and Door Dash all saw increases of more than 500% in online search activity during and after the game, while financial/trading apps like Robinhood and Etrade saw only minor increases.
Chipotle, Doritos, and M&Ms saw the greatest impact on social media channels during and after the Super Bowl, though Toyota also managed to generate a 40% increase in tweets from its ads this year.
Auto manufacturers and Super Bowl advertising
The Super Bowl has traditionally been a battleground for auto manufacturers, a platform for new product launches and a way to put new campaigns in front of a massive audience. Although recent Super Bowl heavies like Kia and Hyundai sat this year out, we still saw fierce competition from auto brands for viewers' attention this year. Brands who did so saw an increase in online activity around their brands, though Cadillac was the clear winner in this regard, generating a more than 330% increase in search activity during the Super Bowl. GM's push on electric vehicles also appears to have garnered significant interest, more than doubling the brand's search interest from prior weeks.
For Americans, this year's Super Bowl may have been a more subdued event but it was more important than ever for advertisers to get their message right. But as we've seen in prior years, for brands the game doesn't end when the Lombardi trophy is handed out – consumer interest for brands shown during the Super Bowl will be higher in the weeks following. It's up to those brands to capitalize by making the Super Bowl part of an omnichannel strategy that follows up on the awareness boost generated to drive consumers toward action.

I think I talked about this million times. I live my weekdays for the brunch time at the weekends. This is my long-time tradition since my years in Istanbul. I've loved that to meet my friends from the university during the weekend to catch up on our lives.
I am still religiously following my brunch all weekends. I think New York is one of the best places to check all these new cool places. Because you can find all these different cuisines from all around the world. My list is a classic list that you can mostly find places with the best Eggs Benedict, pancakes and omelettes. Here are my 5 Best Brunch Places in Brooklyn for Pancakes and Eggs Benedicts.
This place is my favourite ever. I've never had a disappointment with any of my decisions in this restaurant. Classic Moroccan dishes or any other American food. You can't go wrong with any of them. My favourite plate is Black Stone Benedict which is with roasted tomato. Yummy!!!
Seriously their ricotta pancake is the best pancake I've ever eaten. But be prepared to wait at least 30 min for outside sitting. My husband also loves their Moroccan Scramble Egg plate. It's a very interesting one indeed.
I only ate pancakes in Reynards. Those are one of the best dishes I've eaten really. Especially the one made in bites sizes with creme fresh and grapes around was so good.
If you are a drinker in your brunch this place made for you. They have very yummy cocktails. But as always I go with "the Pancake". Here is another approach to pancake. It's definitely on my top 5 list.
I hope you enjoy my Brooklyn list for the best Brunch Places in Brooklyn for Pancakes and Eggs Benedicts.

Where to go for a party?
Party life of the island is taking place mainly in a city Laganas, on the southern-east shore of the island. The most popular are clubs on the open-air.
Of course, on Zakynthos there aren't beaches where no one shows up. It is possible though to find such, where beachgoers are far fewer. We recommend Ambolua on the northern shore, close to a town Nemerilos.
On the eastern shore of an peninsula Skinari there are situated Blue Coves made by erosion. The name refers to colour, with whose interiors of coves are filled thanks to turquoise hue of the sea.
What's worth seeing in Zakynthos?
A small Greek island surprises with its diversified vegetation. In the west dominating are cliffs and mountain terrain, whereas east is full of beautiful, sandy beaches. The central part of the island is used for wineries, whereas in the south you can meet turtles.
The city Zakynthos was hugely destroyed during an earthquake from 1953. With time, there has been attempts to rebuilt foregone architecture. In the city's centre you will see many beautiful buildings, but it gets interesting on a peak of a hill covered with forest. From there you can admire a marvellous panorama of Zakynthos and the whole island. It is not the only reward for an uphill walk. On a hill there is situated an old, Venetian fortress, erected in spot of an ancient citadel.
The most beautiful beach on the island, Navagio, the bay of Shipwreck, is also called the bay of smugglers. Legend goes that situated there shipwrecks belonged to smugglers. There is no way to get there on foot from the island, as beaches are surrounded by huge rocks. The only way is via the sea.
You can't deny charm the beach Gerakas in the south, where entrance is ticketed, and tourists can't spend there more than three hours. By night the entrance is forbidden. It is all due to concern for sea turtles caretta. Their calmness is guarded all the time by volunteers.
If you are looking for traditional, Zakynthos village, go to a peninsula Keri in the south, where you will find preserved houses, a lighthouse and an old port, that weren't destroyed during an earthquake in 1953. If you are not afraid of heights, we recommend climbing to a lighthouse, from where there is a lovely view. Visit one of nearby olive's groves, to buy exquisite, local olives oil straight from farmers. Similar architecture you can find in the second village, that has survived to this day – it's Volimes, located on the northern edge of the island.


The Composition L-Foot Flashing provides a lasting watertight flush installation on composite shingle pitch roofs. It is installed without cutting any shingles. The steel flashing is 12" by 12" and has a 1" slotted bolt connection to attach the L-Foot (L-Foot not included). It comes in clear and black, galvanized steel and anodized aluminum to fit any roof preference.


Cloudflare this week announced it has turned on Encrypted SNI (ESNI) across all of its network, making yet another step toward improving user privacy.
The Transport Layer Security (TLS) Server Name Indication (SNI) extension was introduced to resolve the issue of accessing encrypted websites hosted at the same IP address. Before that, when a request was made for a HTTPS connection, the web server would only hand a single SSL certificate per IP address.
With SNI, however, if a web server hosts multiple domains, the request is routed to the correct site and the right SSL certificate is returned. This ensures that content is encrypted correctly and browsers widely adopted the TLS extension after its specification was introduced by the IETF in 2003.
The issue with SNI, however, is that it leaks the identity of the sites that the user visits. Thus, although the connection to the website is encrypted via HTTPS and the contents sent to and from the site are kept secure, information about the accessed websites isn't.
"Today, as HTTPS covers nearly 80% of all web traffic, the fact that SNI leaks every site you go to online to your ISP and anyone else listening on the line has become a glaring privacy hole. Knowing what sites you visit can build a very accurate picture of who you are, creating both privacy and security risks," Cloudflare's Matthew Prince points out.
SNI requires clients to specify which site they want to connect to during the initial TLS handshake, but, as the client and server don't share an encryption key yet, the ClientHello message is sent unencrypted.
This, however, changes with ESNI, which encrypts the SNI even if the rest of the ClientHello message remains in plaintext.
ESNI works by fetching a public key the server publishes on a well-known DNS record and replacing the SNI extension in ClientHello with a variant encrypted using a symmetric encryption key derived using the server's public key.
The server can derive the symmetric encryption key (given that it owns the private key), and can then terminate the connection or forward it to a backend server. Only the client and the server can derive the encryption key, meaning that the encrypted SNI cannot be decrypted and accessed by third parties, Cloudflare's Alessandro Ghedini notes.
ESNI is an extension to TLS version 1.3 and above, meaning that it doesn't work with previous versions of the protocol. TLS 1.3 moves the Certificate message sent by the server to the encrypted portion of the TLS handshake (it was sent in plaintext before), thus preventing the attacker to determine the identity of the server through observing the plaintext certificates.
The client's ESNI extension also includes the client's public key share, the cipher suite it used for encryption, and the digest of the server's ESNI DNS record, while the server generates a decryption key using its own private key share and the public portion of the client's share. This ensures the encryption key is cryptographically tied to the TLS session it was generated for and cannot be reused.
To avoid exposing all ESNI symmetric keys generated from a server if the server's private key is compromised, Cloudflare's own SNI encryption implementation rotates the server's keys every hour, yet also keeps track of the keys for the previous few hours to allow for DNS caching and replication delays.
Further privacy protections are ensured through features such as DNS over TLS (DoT) and DNS over HTTPS (DoH), which are provided through public DNS resolvers such as Cloudflare's 1.1.1.1. One can, however, determine the visited websites by looking at the destination IP addresses on the traffic originating from users' devices.
With Encrypted SNI now enabled across Cloudflare's network, all of the company's customers can take advantage of it, for free. It still requires browsers to adopt it, and Mozilla is expected to release the first supporting Firefox Nightly this week. The ESNI spec is still under development, so it's not stable just yet.
"Encrypted SNI, along with TLS 1.3, DNSSEC and DoT/DoH, plugs one of the few remaining holes that enable surveillance and censorship on the Internet. More work is still required to get to a surveillance-free Internet, but we are (slowly) getting there," Ghedini concludes.

(1) Overview of Operating Results
During the six months ended September 30, 2021 (from April 1, 2021 to September 30, 2021), the Group made efforts to enhance corporate value over the mid to long term by working to form an earnings base on the two approaches of working to entertain and to serve and by evolving into a new, unique kind of tech company, encouraging synergy between the two approaches. The Group also challenged itself to achieve leaps in growth to establish an even stronger business portfolio.
During the six months ended September 30, 2021, revenue decreased year-on-year mainly due to the decrease in revenue in the Game Business, despite the growth of the Live Streaming Business and the recovery of the Sports Business compared to the same period of the previous year.
Cost of sales increased year-on-year due to the increase in commission fees, etc., which fluctuate in line with the performance of the Live Streaming Business and the Game Business.
Changes in selling, general and administrative expenses were limited compared to the same period of the previous fiscal year.
Other income, net was ¥5,605 million, decreasing from ¥10,058 million in the same period of the previous fiscal year. For the six months ended September 30, 2021, the Company recorded a gain on step acquisitions of ¥2,273 million as a result of the acquisition of all the shares of IRIAM Inc. and compensation of ¥2,090 million for loss on suspension of operations of the Yokohama DeNA BayStars Baseball Club, and included them in other income. In the same period of the previous fiscal year, the Company recorded a gain on transfer in the amount of ¥2,045 million due to an absorption-type company split of businesses related to taxi dispatch apps, etc., and a gain on sales of shares of subsidiaries of ¥7,889 million following the transfer of a portion of the Company's shares in SHOWROOM Inc.
Share of profit of associates accounted for using the equity method was ¥12,303 million, up 397.7% year-on- year. This was due to the performance trends of Cygames, Inc. and Mobility Technologies Co., Ltd., the major associates accounted for using the equity method during the six months ended September 30, 2021, as well as the recording of a one-time gain from the capital increase of Mobility Technologies Co., Ltd. through a third-party allotment, which was conducted during this period.
As a result, revenue of the DeNA Group was ¥68,085 million, down 1.0% year-on-year, operating profit was ¥13,345 million, down 36.2% year-on-year, profit before tax was ¥27,834 million, up 6.7% year-on-year, and profit for the period attributable to owners of the parent was ¥22,684 million, up 18.4% year-on-year.
Business performance by segment is as follows.
Game Business
Revenue of the Game Business was ¥38,808 million, down 16.8% year-on-year, and segment profit was ¥6,398 million, down 42.1% year-on-year.
During the six months ended September 30, 2021, both revenue and profit decreased as operations became centered on existing titles and virtual currency consumption decreased year-on-year. However, during the second quarter ended September 30, 2021, we made progress in the releases of new titles to strengthen the earnings base.
Revenue of the Sports Business was ¥9,439 million, up 41.6% year-on-year, and segment profit was ¥700 million, compared with segment loss of ¥1,024 million for the same period of the previous fiscal year.
The current official professional baseball season began on March 26, 2021. However, games are being played with various measures to prevent the spread of COVID-19, including restrictions on the number of spectators. Since Tokyo 2020 was held during the second quarter ended September 30, 2021, the number of official professional baseball games hosted and held in Yokohama Stadium was fewer than that during this time in an average year.
In the previous season, the official professional baseball games commenced on June 19, 2020, later than a normal season, and at first games were held without spectators due to the spread of COVID-19.

Stefanie Schmitz — Brazilian Music and Rhythms
February 1, 2016 /in CWM News, World Music in the Schools/by Monica Emery
Congratulations to Stefanie Schmitz, Teaching Artist for the World Music in the Schools program, for winning a grant from Rising Arts Leaders to attend the Teaching Artist Institute.
Multi-instrumentalist musical artist and teacher Stefanie Schmitz has been exploring the San Diego music scene since 2001. Her talents span an eclectic range of genres including jazz, classical, samba, choro, funk, musical theatre, playing the clarinet, tenor saxophone, Brazilian percussion, and more. Stefanie attended the University of California San Diego where she received bachelor's degrees in Music Performance and in French Language Studies. She directs and performs with a number of San Diego-based music groups, including Choro Sotaque, Super Sonic Samba School, the Zicas, and Restoration One. She shares the same knowledge and enthusiasm she exhibits as a band leader with her students, teaching private and group lessons on clarinet, saxophone, and percussion to students over a range of ages and ability levels. As a teaching artist for the Center for World Music, she also works in school classrooms, sharing her passion for Brazilian rhythm with San Diego area K–12 students.
Under the sponsorship of the Center for World Music, Stefanie was selected in November 2015 to participate in the Teaching Artist Institute, a professional development program offered by Arts for Learning, an affiliate of Young Audiences/Arts for Learning. For a working musician who collaborates with schools as a teaching artist, this program is of tremendous value. Stefanie was awarded a matching grant from Rising Arts Leaders of San Diego to support her participation in the Teaching Artist Institute.
"In addition to learning about child development, lesson planning, and classroom management, I am connecting with other local teaching artists and developing my own personal mission statement as a performer, learner, and teacher. I'm looking forward to sharing my new energy and ideas with my students!"
Stefanie's love affair with Brazilian music began when she took a samba drumming class. She started San Diego's first choro group Choro Sotaque in 2009, performing traditional Brazilian folk music on clarinet. The group recorded its debut CD in 2015, which is available for purchase at chorosotaque.bandcamp.com. Stefanie has also performed with and led the community based Brazilian drum and dance group Super Sonic Samba School — a group which performs regularly for festivals and events around San Diego. Stefanie seeks out her yearly fix of new inspiration at California Brazil Camp — a weeklong music and dance camp in the redwoods of Sonoma County. In 2013 she left her staff position at UC San Diego to embark on a six-month musical odyssey to Brazil, where she absorbed Brazilian language and culture, and studied with masters of samba and choro in Rio de Janeiro, São Paulo, Olinda, and Jericoacoara.
As an associate artist for Lamb's Players Theatre, Stefanie has played in the orchestras for several musicals, most recently in West Side Story. She also plays saxophone for the eclectic funk/rock/reggae band Restoration One, which was nominated for a 2014 San Diego Music Award. Most recently, she can be seen playing and singing with the Zicas, a new Brazilian music project.
When Stefanie is not playing music or teaching, you will find her making art, tap dancing, practicing yoga, or singing in her car. She blogs about her musical adventures at Everything Is Music, stefanieschmitz.blogspot.com, and she sells her original handmade jewelry in San Diego coffee shops and on Etsy.
Check out Stefanie's website at www.stefanieschmitz.net for her upcoming performance schedule or to sign up for her mailing list.
