DESCRIPTION:Speakers: Viljami Leino (University of Helsinki)\nWe present p
reliminary results of the gradient flow running coupling in SU(2) gauge th
eory with 6 massless fundamental representation fermion flavours. We use t
he Schrödinger functional boundary conditions\, which allows us to also m
easure the mass anomalous dimension. Our results\, using the HEX-smeared W
ilson-clover action\, are consistent with perturbative running on the weak
coupling region and diverge towards a possible infrared fixed point at st
rong coupling.\n\nhttps://conference.ippp.dur.ac.uk/event/470/contribution

DESCRIPTION:Speakers: Martin Hansen (CP3-Origins\, University of Southern
Denmark)\nWe present new results from our ongoing study of the SU(3) "sext
et model" with two flavors in the 2-index symmetric representation of the
gauge group. The simulations use unimproved Wilson fermions and to address
the issue of whether or not the model is inside the conformal window\, we
measure the meson and baryon spectrum. To better understand the overall b
ehavior of the lattice model we map out the bare parameter space\, which r
eveals a non-trivial phase structure. At strong bare coupling\, a first or
der phase transition is observed as a function of the bare mass\, whereas
closer to the continuum limit this first order transition disappears. Our
study also shows that the behavior of mass spectrum (as a function of the
quark mass) changes significantly when moving away from the bulk phase and
into the weak coupling phase.\n\nhttps://conference.ippp.dur.ac.uk/event/

in the adjoint representation\, where each Majorana fermion\ncorresponds
effectively to half a Dirac flavour $N_f$. The most relevant\nexamples for
the extensions of the standard model are supersymmetric\nYang-Mills theor
y ($N_f=1/2$) and minimal walking technicolour ($N_f=2$). In\naddition to
these theories I will also consider the cases of $N_f=1$ and\n$N_f=3/2$.\n
The results will contain the particle spectrum of glueballs\, triplet and\
nsinglet mesons\, and possible fractionally charged spin half particles.\n
In addition I will discuss our recent results for the mass anomalous\ndime

DESCRIPTION:Speakers: Axel Maas (University of Graz)\nThe spectacular succ
ess of perturbation theory in electroweak physics hinges on the validity o
f the Froehlich-Morchio-Strocchi mechanism. This mechanism allows the dete
rmination of the spectrum of physical\, gauge-invariant states using pertu
rbation theory if a Brout-Englert-Higgs effect is present. For this mechan
ism to work two preconditions have to be met. One is the structural requir
ement that the perturbative multiplet structure can be mapped to the physi
cal one. The other requires that dynamically the pole structure of gauge-d
ependent correlation functions is not qualitatively altered. To assess the
validity of perturbation theory to describe the spectrum in beyond-the-st
andard model calculations requires to understand when these conditions are
fulfilled.\n\nThe second condition will be investigated in the Yang-Mills
-Higgs case on the lattice. It is found that it depends crucially on the p
arameters whether this condition is fulfilled. Even in cases where perturb
ation theory should be expected to work well it turns out that it does not
. Various possibilities for a criterion for this breakdown will be discuss
ed. As a side-effect the physical spectrum of the theory in a wide range o
f the phase diagram is uncovered\, which is also valuable for several othe
r research directions.\n\nhttps://conference.ippp.dur.ac.uk/event/470/cont

DESCRIPTION:Speakers: Benjamin Svetitsky (Tel Aviv University)\nThe SU(4)
gauge theory with two flavors of Dirac fermions in the sextet representati
on shares features of a candidate for a composite Higgs model. The analogu
e of the Higgs multiplet of the Standard Model lives in the Goldstone mani
fold resulting from spontaneous breaking of the global symmetry SU(4) to S
O(4). The Higgs potential arises from interaction with the particles of th
e Standard Model. We have computed the gauge boson contribution to the Hi
ggs potential\, using valence overlap fermions on a Wilson-clover sea. The
calculation is similar to that of the electromagnetic mass splitting of t
he pion multiplet in QCD.\n\nhttps://conference.ippp.dur.ac.uk/event/470/c

with two quark flavours in the fundamental\nrepresentation are among the
most promising theories of composite dynamics\ndescribing the electroweak

we expect a spectrum of excitations which appear as\nresonances in vector
boson scattering\, in particular the vector resonance\ncorresponding to th
e rho-meson in QCD.\n\nIn this talk I will present the preliminary results
of the first calculation\nof the rho-meson decay width in this theory\, w
hich is analogous to rho to\ntwo pions decay calculation in QCD. The resul
ts presented were calculated\nusing 2 moving frames on s single ensemble.
Future plans include using 3\nmoving frames on a larger set of ensembles t
o extract the resonance\nparameters more reliably and also take the chiral
and continuum limits.\n\nhttps://conference.ippp.dur.ac.uk/event/470/cont

DESCRIPTION:Speakers: Joel Giedt (Rensselaer Polytechnic Institute)\nFormu
lations of lattice supersymmetry over the last decade have been able to si
gnificantly reduce the amount of fine-tuning necessary in order to obtain
the correct continuum limit. In the case of N=4 super Yang-Mills\, the ap
proach that has emerged as the best path forward is based on a topological
twisting of the theory. Montonen and Olive found evidence that a duality
could exist in Yang-Mills with adjoint scalars. In this scheme\, the 't H
ooft-Polyakov monopole is dual to the W boson\,leading to a theory equival
ent to the original one\, but with magnetic charge replacing electric char
ge. The duality is believed to be realized in N=4 super-Yang-Mills. We a
re pursuing numerical\, nonperturbative evidence for this S-duality using
our lattice formulation. The various tricks that are necessary for doing t
his will be described.\n\nhttps://conference.ippp.dur.ac.uk/event/470/cont

y on the discretized curved space both from theoretical and numerical poin

ntinuum $\\mathcal{N}=(2\,2)$ SYM theory on any curved manifold is enhance
d to two by considering an appropriate $U(1)$ gauge backgrounds associated
with the $U_{V}(1)$ symmetry.\nWe then show that the generalized Sugino m
odel\, which was proposed in our previous work\, \ncan be identified to th
e discretization of the SUSY enhanced theory\, \nwhere one of the supersym
metries is kept and the other one is restored in the continuum limit.\nThe
$U_{A}(1)$ anomaly of the continuum theory is maintained also in the disc
retized theory as an unbalance of the number of the fermions. \nWe study t
he discretized supersymmetric model based on the numerical Monte-Carlo sim
ulation.\nIn the process\, we propose a novel phase-quenched approximation
\, which we call the ``anomaly-phase-quench approximation".\nWe find that
the Ward-Takahashi (WT) identity expected from the analytical study realiz
es in the model and there is no sign-problem by adopting the anomaly-phase
-quench method. \nThe result is the first numerical observation for the su
persymmetric lattice model on the curved space with generic topologies.\n\

n the ultraviolet it exhibits the properties of the $N_f=12$ conformal fix
ed point. The running coupling of this system ``walks" and the energy rang
e of walking can be tuned by the mass of the heavy flavors. At the same ti
me\, renormalization group considerations predict the spectrum of such a s
ystem to show hyperscaling i.e. hadron masses in units of $F_\\pi$ are ind
ependent of the heavy mass. Hyperscaling is present for bound states made-
up of light\, heavy\, or heavy and light flavors. This observation is supp

DESCRIPTION:Speakers: Anosh Joseph (University of Cambridge)\nMaximally su
persymmetric Yang-Mills theory in five dimensions has generated a lot of i
nterest in the recent years. It takes part in the gauge-gravity duality an
d its finite temperature properties have been investigated recently in the
planar limit. This theory is also interesting through its conjectured rel
ationship to the six-dimensional (2\,0) theory\, which is still controvers
ial. In this talk we describe the lattice construction of D=5 maximally su
persymmetric Yang-Mills theory. The lattice theory preserves one superchar
ge exact at finite lattice spacing. This supersymmetric lattice formulatio
n can be used to explore the non-perturbative regime of the continuum targ
et theory. It would be interesting to find a nontrivial UV fixed point fro
m the lattice theory for D=5 theory since the fixed point can provide a UV
completion and non-perturbative definition of the theory.\n\nhttps://conf

we are exploring a range of 't Hooft couplings for two-\, three- and four

strong-coupling AdS/CFT duality in the large-N limit. Among the various

DESCRIPTION:Speakers: George Fleming (Yale University)\nThe LSD Collaborat
ion has recently completed a study of the light hadron spectrum in SU(3) g
auge theory with eight light\, degenerate flavors. We have observed that
the lightest isosinglet scalar meson\, also called the sigma\, remains ess
entially degenerate with the pions even when the (pi\,sigma) multiplet mas
s scale falls below half the rho meson mass as a function of the input qua
rk mass. This is clearly quite different from QCD with two light flavors.
However\, we also observe behavior consistent with the vector meson domi
nance (VMD) hypothesis\, which is quite similar to QCD with two light flav
ors. Finally\, we discuss how the presence of a light sigma in the spectr
um affects the standard methodology of lattice gauge theory calculations.\

DESCRIPTION:Speakers: Andrew Gasbarro (Yale University)\nIn recent years\,
lattice studies of multi-flavor gauge theories near and inside the confor

ates in their spectra\, which has led to a renewed interest in strong dyna
mics as a solution to the Higgs hierarchy problem. An additional requirem
ent to realize a UV complete composite Higgs sector is that observables of
low energy scattering be in close agreement with the linear sigma model.
We will compute the momentum dependence of the scalar form factor of the
pion and of the scattering phase shift of I=2 pi-pi scattering. These qua
ntities will be compared to the linear sigma model and other low energy ef
fective theories. We will also study the vector form factor to test the a
nsatz of vector meson dominance and to compare to I=1 scattering in a futu
re study. This talk reports on the current progress.\n\nhttps://conferenc

that of the elementary particles. This works because of the special stru

operators as well as interesting collider signatures. Non-perturbative rel

DESCRIPTION:Speakers: Marco Garofalo (University of Edinburgh)\nWe conside
r a field theoretical model where a SU(2) doublet fermion\, subjected to n
on-abelian gauge interactions\, is also coupled to a complex scalar field
doublet via a Yukawa and an irrelevant Wilson-like term. Despite the prese
nce of these two chiral breaking operators in the Lagrangian\, an exact sy
mmetry acting on fermions and scalars prevents perturbative mass correctio
ns. In the phase where fermions are massless (Wigner phase) the Yukawa cou
pling can be tuned to a critical value at which chiral transformations act
ing on fermions only become a symmetry of the theory (up to cutoff effects
). In the Nambu-Goldstone phase of the critical theory a fermion mass term
of dynamical origin is expected to arise in the Ward identities of the pu
rely fermionic chiral transformations. Such a non-perturbative mechanism o
f dynamical mass generation can provide a “natural" (a` la 't Hooft) alt

of large mass hierarchies\, we investigate the theoretical possibility tha
t these could arise dynamically in new strongly-coupled gauge theories ext
ending the standard model of particle physics. To this purpose\, we study
lattice data on non-Abelian gauge theories in the (near-)conformal regime
—specifically\, $\\mathrm{SU}(2)$ with $N_{\\mathrm{f}}=1$ and $2$ dynam
ical fermion flavours in the adjoint representation. We focus our attentio
n on the ratio $R$ between the masses of the lightest spin-2 and spin-0 re
sonances\, and draw comparisons with a simple toy model in the context of
gauge/gravity dualities. For models in which large anomalous dimensions ar
ise dynamically\, we show indications that this mass ratio can be large\,
with $R > 5$. Moreover\, our results suggest that $R$ might be related to
universal properties of the IR fixed point. Our findings provide an intere
sting step towards understanding large mass ratios in the non-perturbative
regime of quantum field theories with (near) IR conformal behaviour.\n\nh

Albeit the standard model is the most successful model of particles physic

of the standard model could be a possible solution to these problems.\n\nO

e.\nWe present new results on N=2 Super Yang Mills theory in two dimension
s. The lattice action is derived by a dimensional reduction of the N=1 Sup
er Yang Mills theory in four dimensions. By preserving the R symmetry of t
he four dimensional model we can exploit Ward identities to fine tune our
parameters of the model to obtain the chiral and supersymmetric continuum
limit. This allows us to calculate the mass spectrum at the physical point
and compare these results with effective field theories.\n\nhttps://confe
