c)\nHeavy Vector resonances are a general prediction of Composite Higgs Th
eories\, where the Higgs arises as a pseudo Nambu Goldstone Boson. Typical
ly at the LHC these states are sought for via narrow resonant searches\, l
ooking for "bumps" in the dilepton invariant mass spectrum. These states c
an however undergo decays into a pair of top partners in a large and natur
al range of Composite Higgs theories parameter space\, thus evading curren
t LHC limits. We however show how\, by reinterpreting LHC analyses designe
d for top partners searches\, strong limits can be set on these otherwise
elusive resonances\, highlighting the prospect for these searches at the r

hases. The tight-binding model defined on the Lieb lattice with three diff
erent species of fermions supports a single Dirac-like point in the moment
um space. The dispersion relation around this point is fully relativistic
and described by a Duffin-Kemmer-Petiau Hamiltonian. I show the presence o
f topologically protected edge states by employing the entanglement spectr
um. Importantly\, these edge modes become Majorana modes by introducing su
itable Cooper pairings in the lattice. This model represents the first exa

of topological phases of condensed matter can be "inferred" from their bou

bulk topological order.\nIn particular\, I will demonstrate that one can
extract the so-called modular S and T matrices from boundary theories.\nTh

braiding statistics of topological excitations in the bulk.\nhttps://agen

DESCRIPTION:Speakers: Zvi Bern (UCLA)\nFor the past 30 years nearly all th

nstein's general relativity necessarily must be ill-defined in the ultravi
olet. This is the well known nonrenormalizability problem of gravity. But
is it actually true in general? We describe recent calculations that cas
t doubt on this simple picture and show that quantum gravity is much tamer
in the ultraviolet than believed possible. The new calculations make use
of enormous advances in our ability to compute scattering amplitudes in qu
antum field theory. The relationship between gravity and gauge theory als
o offers a more general promise of simplifying Einstein’s Theory of Gene
ral Relativity\, as will be illustrated with black hole solutions.\nhttps:

single scalar field\, the "adiabatic" mode. The current explanations are p

DESCRIPTION:Speakers: Eduardo Grossi (University of Florence &\; INFN F
lorence)\, Francesco Becattini (FI)\nWe show that the stress-energy tensor
has additional terms with respect to the ideal form in states of global t
hermodynamic equilibrium in flat spacetime with non-vanishing acceleration
and vorticity. These corrections are of quantum origin and their leading
terms are second order in the gradients of the thermodynamic fields. Their
relevant coefficients can be expressed in terms of correlators of the str
ess-energy tensor operator and the generators of the Lorentz group. With r
espect to previous assessments\, we find that there are more second-order
coefficients and that all thermodynamic functions including energy density
receive acceleration and vorticity dependent corrections. We have calcula
ted the corrections for a free real scalar field—both massive and massle
ss- and also for complex scalar field and Dirac field with finite chemic
al potential\, and are generally non-vanishing also for a free theory.\nFi
nally\, these nonideal terms depend on the explicit form of the stress-ene
rgy operator\, implying that different stress-energy tensors are thermodyn

mass in this limit. The computation is done on the lattice implementing t

coincide with the correct field-theoretic quantity in the continuum limit
. High-statistics Monte Carlo simulations of lattice-regularized SU(N) Yan
g–Mills theory\, with N=3\, 4\, 5\, 6 and for three different lattice sp

n are employed to avoid the freezing of the topological charge both for fi

argue that the imaginary parts originates entirely from a non--trivial fra

in the heavy quark region\,\nnew symmetry plays an important role.\nThe sy

of the\nstates with different total spin\, e.g. the mass degeneracy of th
e heavy\npseudoscalar and vector mesons.\nIt is important to generate the
exotic hadron structures found in the heavy\nquark region.\n\nThe mass deg
eneracy enhances the mixing of $D$ ($J^P=0^-$) and $D^\\ast$\n($J^P=1^-$)
mesons.\nTherefore the pion coupling $\\pi DD^\\ast$ is introduced\,\nwhil
e the coupling $\\pi DD$ is forbidden.\nIt is known that the one pion exch
ange potential (OPEP)\nis important for the binding of atomic nuclei.\nThe
attraction of the OPEP motivates us to investigate\nnew meson-nucleus sys
tems in the heavy quark region.\nIn this talk\, we study\nbound and resona
nt states of hadronic molecules of a heavy meson and\na nucleon.\n\nIn add
ition\, the mass degeneracy can appear in not only the ordinary\nhadrons b
ut also hadronic molecules.\nIt indicates the existence of partner states
of the heavy quark symmetry.\nWe also discuss the properties of the hadron

strong coupling the scattering amplitudes can be computed solving a minam
al area problem\, thanks to the AdS/CFT correspondence.\n As for the Wilso

developed enabling us to write it as a sum over the excitations on the GKP
vacuum. Thanks to the integrability underlying the theory\, we have been
obtaining many exact results in a series of papers\, mainly on the strong
coupling limit. Among them\, the computation of the\n Wilson loop is recas
t into a system of TBA-like equations\, finding agreement with the classic

or the related Wilson loops. While consistent with previous perturbative a

to distinguish the two case with the introduction of the time in the sadd

DESCRIPTION:Speakers: Marco Polini (Istituto Italiano di Tecnologia\, Grap
hene Labs)\nGraphene sheets encapsulated between crystals of boron nitride
host a unique electron system that due to weak electron-phonon scattering
allows micrometer-scale ballistic transport even at room temperature [1\,
2\,3\,4]. Above liquid nitrogen temperatures\, these electron liquids are
expected to display local equilibrium\, enabled by strong electron-electro
n interactions [5]. Under these conditions\, electrons in doped samples ar
e expected to behave as a viscous liquid and may exhibit hydrodynamic phen
omena akin to those observed in classical and quantum liquids. In this tal
k I will report on results of combined theoretical and experimental work [
6\,7] showing unambiguous evidence for this long-sought transport regime.
In particular\, I will discuss how high-quality graphene sheets in the Fer
mi liquid regime (k_B T ≲ E_F) exhibit an anomalous (negative) voltage d
rop near current injection points\, which is attributed to the formation o
f whirlpools in the electron flow. Measurements of these quasi-local elect
rical signals enable to extract the value of the kinematic viscosity of th
e two-dimensional massless Dirac fermion liquid in graphene\, which is fou
nd to be an order of magnitude larger than that of honey\, in quantitative
agreement with many-body theory [8]. Finally\, I will discuss how our res
ults near the charge neutrality point (k_B T≫ E_F) are compatible with t
he AdS/CFT viscosity bound [9\,10]. \nOur work represents the first step t

ttering at\ntransplanckian energies ($E \\gg M_P$) and small deflection an
gles. We show that\n--- owing to the graviton's spin 2 --- such limiting
form unifies the soft- and\nRegge- regimes of emission\, by covering a bro
ad angular range\, from forward\nfragmentation to deeply central region. T
he single-exchange emission amplitudes\nhave a nice expression in terms of
the transformation phases of helicity\namplitudes under rotations. As a r
esult\, the multiple-exchange emission\namplitudes can be resummed via an
impact parameter $b$-space factorization\ntheorem that takes into account
all coherence effects. We then see the emergence\nof an energy spectrum of
the emitted radiation which\, being tuned on $\\hbar/R\\sim M_P^2/E \\ll
M_P$\, is reminiscent of Hawking's radiation. Such a spectrum is\nmuch sof
ter than the one naively expected for increasing input energies and\nneatl
y solves a potential energy crisis. Furthermore\, by including rescatteri
ng\ncorrections in the (quantum) factorization formula\, we are able to re
cover the\nclassical limit and to find the corresponding quantum correctio
ns. Perspectives\nfor the extrapolation of such limiting radiation toward

of massive spin-2 particles. We note that their action in the vielbein for
mulation admits a natural extension in terms of integral forms on a superm
anifold\, which will be locally supersymmetric by construction\, and thus
will describe a new class of couplings between supergravity and massive sp
in-2 multiplets. We propose superfield actions for N=1 multimetric supergr

If (some of) these matter particles\, as the Higgs doublets\, become stro

s the correct enhancement of the tree level Higgs boson mass required to r
each 125 GeV. It is conceivable that the Yukawa couplings to the singlet\,
although naively blowing up close to Λ\, will not spoil gauge coupling u
nification. In such a case the unified coupling could be interestingly led
to a value not far from unity\, thus providing a possible explanation for
the number of generations. The characteristic signal is an enhanced reson
ant production of neutral spin zero particles at LHC\, that could even exp
lain the putative diphoton resonance hinted by the recent LHC data at 750

ons of the European Twisted Mass Collaboration (ETMC) with Nf = 2+1+1 dyna
mical quarks. These are particularly suitable for charm physics\, as the s
trange and charm quark masses are close to their physical values. Otherwis
e the extension to the beauty-sector requires an extrapolation\, in order
to do that\, the ETMC ratio method has been applied.\nhttps://agenda.infn.

SUMMARY:The quench action approach in finite integrable spin chains

DESCRIPTION:Speakers: Vincenzo Alba (SISSA)\, Pasquale Calabrese (SISSA)\n
We consider the problem of constructing the stationary state following a q
uantum quench\, using the exact overlaps for finite size integrable models
. We focus on the isotropic Heisenberg spin chain with initial state N\\'e
el or Majumdar-Ghosh (dimer)\, although the proposed approach is valid for
an arbitrary integrable model. We consider only eigenstates which do not
contain zero-momentum strings because the latter are affected by fictitiou
s singularities that are very difficult to take into account. We show that
the fraction of eigenstates that do not contain zero-momentum strings is
vanishing in the thermodynamic limit. Consequently\, restricting to this p
art of the Hilbert space leads to vanishing expectation values of local ob
servables. However\, it is possible to reconstruct the asymptotic values b
y properly reweighting the expectations in the considered subspace\, at th
e price of introducing finite-size corrections. We also develop a Monte Ca
rlo sampling of the Hilbert space which allows us to study larger systems.
We accurately reconstruct the expectation values of the conserved charged
and the root distributions in the stationary state\, which turn out to ma
tch the exact thermodynamic results. The proposed method can be implemente
d even in cases in which an analytic thermodynamic solution is not obtaina
ble.\nhttps://agenda.infn.it/event/10115/contributions/733/

DESCRIPTION:Speakers: Redigolo Diego (LPTHE_CNRS)\nWe will review Twin Hig
gs constructions in light of SUSY UV completions. Combining the Twin Higgs
and SUSY provides a perturbative solution of the hierarchy problem in whi
ch the low-lying states stabilizing the EW scale are uncharged under the S
M gauge group. We will discuss the fine tuning of the EW scale and the ric
h phenomenology of the Higg sector in a wide class of Twin SUSY models. We
will see how models tuned at the level of 10-20 % can be easily obtained
within this framework and discuss the crucial role played by the Higgs mas
s constraint. We then sketch some distinctive phenomenological features of
this setup which can be relevant for future colliders.\nhttps://agenda.in

SUMMARY:Is the gravitational-wave ringdown a probe of the event horizon?

DESCRIPTION:Speakers: Edgardo Franzin (C)\nIt is commonly believed that th
e ringdown signal from a binary coalescence provides a conclusive proof fo
r the formation of an event horizon after the merger. This expectation is
based on the assumption that the ringdown waveform at intermediate times i
s dominated by the quasinormal modes of the final object. We point out tha
t this assumption should be taken with great care\, and that very compact
objects with a light ring will display a similar ringdown stage\, even whe
n their quasinormal-mode spectrum is completely different from that of a b
lack hole. In other words\, universal ringdown waveforms indicate the pres
ence of light rings\, rather than of horizons.\nOnly precision observation
s of the late-time ringdown signal\, where the differences in the quasinor
mal-mode spectrum eventually show up\, can be used to rule out exotic alte
rnatives to black holes and to test quantum effects at the horizon scale.\

will review recent challenges to WIMP dark matter models and describe how
some of them are addressed by giant 't Hooft-Polyakov monopole models. Th
ese models exist in theories with a dark sector including a dark SU(2) gau
ge symmetry coupled to an adjoint Higgs and two fundamental fermions. Sev
eral consistency checks of such models will be described\, including consi
stency with MACHO bounds and the CMB power spectrum. The main prediction
of such models\, which can soon be tested using GAIA astrometry data\, is
that dwarf galaxies are embedded in halos which extend for tens of kpc\, o
ften beyond their tidal radii\, which would be impossible for gravitationa
lly bound particulate dark matter.\nhttps://agenda.infn.it/event/10115/con

DESCRIPTION:Speakers: Michele Mesiti (PI)\, Claudio Bonati (PI)\, Massimo
D'Elia (PI)\, Francesco Negro (PI)\, Francesco Sanfilippo (Southampton Uni
versity)\, Marco Mariti (PI)\nThe phase diagram of QCD at finite density c
an be studied both experimentally and by theoretical means.\nWhile\, from
the experimental point of view\, it is possible to obtain information from
heavy ion collision experiments\, from the theoretical point of view the
only possible first-princlple approach are Lattice QCD Montecarlo simulati
ons. Unfortunately\, at nonzero baryon density current algorithms are affe
cted by a sign problem. \nNonetheless\, in the regime where the baryon che
mical potential $\\mu_B$ is sufficiently small\, it is possible to make pr
edictions for the dependence of the critical temperature $T_c$ on $\\mu_B$
\, that is the so-called "critical line" of QCD. I will discuss our latest
results in this regard and compare them with the literature.\nhttps://age
