DESCRIPTION:Speakers: Michele Mesiti (PI)\nThe phase diagram of QCD at fin
ite density can be studied both experimentally and by theoretical means.\n
While\, from the experimental point of view\, it is possible to obtain inf
ormation from heavy ion collision experiments\, from the theoretical point
of view the only possible first-princlple approach are Lattice QCD Montec
arlo simulations. Unfortunately\, at nonzero baryon density current algori
thms are affected by a sign problem. \nNonetheless\, in the regime where t
he baryon chemical potential $\\mu_B$ is sufficiently small\, it is possib
le to make predictions for the dependence of the critical temperature $T_c
$ on $\\mu_B$\, that is the so-called "critical line" of QCD. I will discu
ss our latest results in this regard and compare them with the literature.

DESCRIPTION:Speakers: Jarah Evslin (Institute of Modern Physics\, CAS)\nI
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.\n\nhttps://agenda.infn.it/event/10115/c

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.\

within this framework and discuss the crucial role played by the Higgs mas

DESCRIPTION:Speakers: Vincenzo Alba (SISSA)\nWe consider the problem of co
nstructing the stationary state following a quantum quench\, using the exa
ct overlaps for finite size integrable models. We focus on the isotropic H
eisenberg spin chain with initial state N\\'eel or Majumdar-Ghosh (dimer)\
, although the proposed approach is valid for an arbitrary integrable mode
l. We consider only eigenstates which do not contain zero-momentum strings
because the latter are affected by fictitious 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 thermodynami
c limit. Consequently\, restricting to this part of the Hilbert space lead
s to vanishing expectation values of local observables. However\, it is po
ssible to reconstruct the asymptotic values by properly reweighting the ex
pectations in the considered subspace\, at the price of introducing finite
-size corrections. We also develop a Monte Carlo sampling of the Hilbert s
pace which allows us to study larger systems. We accurately reconstruct th
e expectation values of the conserved charged and the root distributions i
n the stationary state\, which turn out to match the exact thermodynamic r
esults. The proposed method can be implemented even in cases in which an a
nalytic thermodynamic solution is not obtainable.\n\nhttps://agenda.infn.i

DESCRIPTION:Speakers: Aurora Melis (RomaTre University of Rome)\nIn this t
alk the results of a lattice QCD calculation of the vector mesons decay co
nstants are presented. They are relevant hadronic parameters that characte
rize the internal structure of vector mesons due to QCD interactions\, for
instance they can provide phenomenologically good descriptions of non-lep
tonic decay rates within the factorization approximation. The two previous
lattice calculations for these parameters show a 10% difference\, the pre
sented results point to a possible explanation of the existing tension.\nT
he analysis is based on the extraction of mesons masses and decay constant
s from the two-point correlation functions coming from unquenched simulati
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.\n\nhttps://agenda.inf

DESCRIPTION:Speakers: Dario Buttazzo (Universität Zürich)\nWe consider t
he NMSSM extended to include one vector-like family of quarks and leptons.
If (some of) these matter particles\, as the Higgs doublets\, become stro
ngly coupled to the singlet at a common scale Λ ~ 10-1000 TeV\, this give
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
GeV.\n\nhttps://agenda.infn.it/event/10115/contributions/722/

upermanifold\, which will be locally supersymmetric by construction\, and
thus will describe a new class of couplings between supergravity and massi

DESCRIPTION:Speakers: Dimitri Colferai (FI)\nWe derive the limiting form o
f graviton radiation in gravitational scattering at\ntransplanckian energi
es ($E \\gg M_P$) and small deflection angles. 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 broad angular range\, from forward\n
fragmentation to deeply central region. The single-exchange emission ampli
tudes\nhave a nice expression in terms of the transformation phases of hel
icity\namplitudes under rotations. As a result\, the multiple-exchange emi
ssion\namplitudes can be resummed via an impact parameter $b$-space factor
ization\ntheorem that takes into account all coherence effects. We then se
e the emergence\nof an energy spectrum of the emitted radiation which\, be
ing tuned on $\\hbar/R\\sim M_P^2/E \\ll M_P$\, is reminiscent of Hawking'
s radiation. Such a spectrum is\nmuch softer than the one naively expected
for increasing input energies and\nneatly solves a potential energy crisi
s. Furthermore\, by including rescattering\ncorrections in the (quantum)
factorization formula\, we are able to recover the\nclassical limit and to
find the corresponding quantum corrections. Perspectives\nfor the extrap
olation of such limiting radiation towards the classical collapse\nregime
(where $b$ is of the order of the gravitational radius $R$) are also\ndisc
ussed.\n\nhttps://agenda.infn.it/event/10115/contributions/716/

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
owards the observation of nearly perfect fluidity and turbulence in solid-
state devices.\n\nhttps://agenda.infn.it/event/10115/contributions/712/

omy. Motivated by the recent experimental result\, I will review recent re
sults about analytical effective-one-body (EOB) approach to the general-re
lativistic two-body dynamics\, notably its completion using numerical rel
ativity (NR) simulations\, stressing its necessity to compute the (thousan
ds of) analytical waveform templates needed for the actual data analysis o
f GW events like GW150914.\nI will mainly report on recent result about th
e EOB(NR) approach concerning: (i) the coalescence of (spinning) black hol
e binaries (BBHs)\, showing the performance of a recently completed\, NR-
informed\, EOB model (arXiv:1506.08457) able to generate highly faithful
waveform from the quasi-circular inspiral\, through plunge\, merger and r

cular emphasis on the modelization of tidal effects up to merger\, whose
measurability in gravitational wave experiments will allow us to put stro
ng constraints on the equation of state of ultra-dense matter\; (iii) the
strong-field scattering of BBHs as a useful numerical laboratory to extra
ct strong-field information to complete the EOB analytical model. \nA cla
ss of effective-one-body waveform templates for coalescing BBHs\, similar
to the one I will discuss during the talk\, has been crucially used in the
recent analysis of the gravitational wave event GW150914\n\nhttps://agend

of a quantum system and the topology of the manifold of particle configur
ations can account for both the breaking of an internal symmetry and the p
resence of an energy gap. Such features are clearly displayed by the quant
um particle on a circle and the Bloch electron\, for instance. \nIn fact\,
the fundamental group of the manifold of the positions of the quantum sys
tem gives rise to elements of the center $\\mathcal Z$ of the observable a
lgebra: symmetries that do not commute with the topological invariants rep
resented by elements of $\\mathcal Z$ are then spontaneously broken in eac
h irreducible representation of the observable algebra compatibly with an
energy gap.\n\nhttps://agenda.infn.it/event/10115/contributions/704/

or number of particles is present two different stationary regimes are re
ached at long times\, depending on the ratio t/L\, where t is the observat
ion time scale and L is the total system size. To captured the two quasi-s
tationary states (before the quantum recurrence) with the QAM is necessary
to distinguish the two case with the introduction of the time in the sadd
le point equation as just shown in a previous paper\, and we show how this
modication works also for a domain wall initial state. We compute the tot
al time evolution for three different initial state of a XX chain\, conjec
turing that our master equation is valid for any initial state. We also re
view the derivation of the GGE state in the case of the two temperatures s
howing that this is an effect of finite volume\, as for a domain wall init

confines without breaking the SM gauge symmetry. The new physics is not r

DESCRIPTION:Speakers: Fotis Farakos (University of Padova)\nWhen supersymm
etry is broken and nonlinearly realized\, one may remove from the spectrum
of the theory various component fields. This is achieved by introducing a
ppropriate constraints to the various superfields. We discuss the coupling
of the nilpotent Goldstino superfield to supersymmetry and supergravity\,
and to matter superfields. \nWe also give a generic setup within which on
e can remove any component field from the spectrum. \nWe also discuss appl

g a scaling limit in which the ladder diagrams dominate. The resummation i
s encoded into a Bethe-Salpeter equation that is mapped to a Schroedinger
problem\, exactly solvable due to the surprising supersymmetry of the effe
ctive Hamiltonian. In the ABJ case the solution implies the diagonalizatio
n of the U(N) and U(M) building blocks\, suggesting the existence of two i
ndependent cusp anomalous dimensions and an unexpected exponentiation stru
cture for the related Wilson loops. While consistent with previous perturb
ative analysis\, the strong coupling limit of our result does not agree wi
th the string theory computation\, emphasizing a difference with the analo

DESCRIPTION:Speakers: Alfredo Bonini (BO)\nThe gluon scattering amplitudes
and the null polygonal Wilson loops in planar Super Yang-Mills N=4 are be

\, while at strong coupling the scattering amplitudes can be computed solv
ing a minamal area problem\, thanks to the AdS/CFT correspondence.\n As fo
r the Wilson loops\, a variant of the well-known Operator Product Expansio
n has been 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 lo
op is recast into a system of TBA-like equations\, finding agreement with
the classical string result. In addition\, a purely quantum\ncontribution
of the same order of the classical one comes out of the blue by considerin
g an ostensibly sub-dominant sector.\n\nhttps://agenda.infn.it/event/10115

mesons.\nTherefore the pion coupling $\\pi DD^\\ast$ is introduced\,\nwhil

will show how the localization results are reproduced perturbatively and
argue that the imaginary parts originates entirely from a non--trivial fra

BJ(M) the framing phase is a non--trivial function of the couplings and po

DESCRIPTION:Speakers: Marco Cè (SNS & INFN\, Pisa)\nWe present preliminar
y results for the topological charge susceptibility of SU(N) Yang–Mills
theory in the large-N limit. This observable enters the Witten–Veneziano
formula and gives the anomalous contribution to the η' meson mass in thi
s limit. The computation is done on the lattice implementing the gradient
flow definition of the topological charge\, which is proven to coincide wi
th the correct field-theoretic quantity in the continuum limit. High-stati
stics Monte Carlo simulations of lattice-regularized SU(N) Yang–Mills th
eory\, with N=3\, 4\, 5\, 6 and for three different lattice spacings\, has
been performed. Open boundary conditions in the time direction are employ
ed to avoid the freezing of the topological charge both for finer lattices
and larger N. This allows us to extrapolate the result to the continuum l
imit and to the N→∞ limit with confidence\, keeping all the systematic
s negligible with respect to the statistical error.\n\nhttps://agenda.infn

respect to the ideal form in states of global thermodynamic equilibrium in
flat spacetime with non-vanishing acceleration and vorticity. These corre

he gradients of the thermodynamic fields. Their relevant coefficients can
be expressed in terms of correlators of the stress-energy tensor operator
and the generators of the Lorentz group. With respect to previous assessme
nts\, we find that there are more second-order coefficients and that all t
hermodynamic functions including energy density receive acceleration and v
orticity dependent corrections. We have calculated the corrections for a f
ree real scalar field—both massive and massless- and also for complex
scalar field and Dirac field with finite chemical potential\, and are gene
rally non-vanishing also for a free theory.\nFinally\, these nonideal term

DESCRIPTION:Speakers: Michele Della Morte (Dept. Of Mathematics and Comput
er Science\, University of Southern Denamrk)\nWe discuss the relevance of
lattice computations in precision tests of the Standard Model\, with empha
sis on heavy Flavor Physics and Higgs Physics. After a short introduction
to the lattice methodology\, we present recent computations of low energy
hadronic parameters (decay constants and form factors) and quark masses. W
e do that by describing the FLAG initiative\, its scope and the choice of
rating criteria used to assess the quality of different calculations. That
should make clear that the precision reached for a number of quantities i
s such that electromagnetic (EM) corrections\, beyond the point-like appro
ximation\, are becoming relevant. We discuss recent computations of the sp
ectrum based on direct simulations of QED+QCD. We also present theoretical
developments for including EM effects in leptonic decays.\n\nhttps://agen

SUMMARY:A curious story of quantum gravity in the ultraviolet

DESCRIPTION:Speakers: Zvi Bern (UCLA)\nFor the past 30 years nearly all th
eoretical physicists have believed that quantum field theories based on Ei
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.\n\nhttp

physical information in a more and more accurate way.\nI describe the stat

DESCRIPTION:Speakers: Shinsei Ryu (University of Illinois at Urbana-Champa
ign)\nMany of interesting physical (in particular topological) properties
of topological phases of condensed matter can be "inferred" from their bou
ndary (end\, edge\, surface\, ..) field theories. In particular\, the pres
ence of quantum anomalies in boundary field theories (or lack thereof) pro
vides a way to diagnose bulk topological properties. I will discuss such b
ulk/boundary correspondence in various examples in (3+1) d with or without
bulk topological order.\nIn particular\, I will demonstrate that one can
extract the so-called modular S and T matrices from boundary theories.\nTh
ese quantities encode important data of the bulk topological order such as
braiding statistics of topological excitations in the bulk.\n\nhttps://ag

DESCRIPTION:Speakers: Giandomenico Palumbo (University of Utrecht)\nIn thi
s talk\, I propose a new model that supports two-dimensional topological p
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
mple of topological superconductor in two-dimensional trionic phases.\n\nh

DESCRIPTION:Speakers: Daniele Barducci (LAPTh\, Universite Savoie Mt. Blan
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
un-2 of the LHC.\n\nhttps://agenda.infn.it/event/10115/contributions/664/
