DESCRIPTION:Title: Global anomalies in the Standard Model(s) and Beyond\nby Joe
Davighi as part of CERN BSM Forums\n\n\nAbstract\nGlobal anomalies in gau
ge theories are detected by the exponentiated eta-invariant\, which become
s a cobordism invariant when perturbative anomalies vanish. After giving a
gentle introduction to these concepts\, I will analyse global anomalies i
n four distinct (but equally valid) versions of the Standard Model by comp
uting appropriate bordism groups. In two cases we find no global anomalies
beyond the famous Witten anomaly associated with electroweak SU(2) symmet
ry\, while in the other two cases there can be no global anomalies at all.
This is due to an interplay between local and global anomalies in "closel
y related" gauge theories. If there is time\, I will discuss a more subtle
version of this anomaly interplay occurring in a U(2) gauge theory define
d without a spin structure\, and/or global anomalies in BSM theories.\n

DESCRIPTION:Title: Quantum Annealers as a Laboratory for Quantum Physics\nby St
even Adam Abel (University of Durham (GB)) as part of CERN BSM Forums\n\n\
nAbstract\nI discuss recent work done with Michael Spannowsky at Durham in
which we propose quantum annealers as a \nlaboratory for studying non-per
turbative aspects of quantum mechanics and quantum field theories. Our ap
proach encodes the field theory as an Ising model\, which is then solved b
y the annealer. As a proof-of-concept\, we encode a scalar field theory an
d measure the probability for it to tunnel from the false to the true vacu
um for various tunnelling times\, vacuum displacements and potential profi
les. This is the first time it has been possible to experimentally measure
instanton processes in a freely chosen quantum field theory. This novel a
nd flexible probe of quantum systems can in principle be applied to study
any field theory of interest using genuine quantum experimentation. Measur
ements of the dynamical behaviour of field theories are independent of the
oretical calculations and could be used to infer their properties without
being limited by the availability of suitable perturbative or nonperturbat
ive computational methods.\n

DESCRIPTION:Title: Holography of the cosmological phase transition of composite Hig
gs confinement\nby Majid Ekhterachian as part of CERN BSM Forums\n\n\n
Abstract\nI will discuss the cosmological (de)confinement phase transition
(PT) of nearly conformal\, strongly coupled large N field theories\, appl
icable to composite Higgs models\, using their holographic dual 5D formula
tion. In this description\, the PT is from the high temperature phase in
which the IR of the warped extra dimension is covered by a black-brane hor
izon to the low temperature Randall-Sundrum-1 phase. The PT proceeds by pe
rcolation of IR-brane bubbles nucleating from the horizon\, and the bubble
dynamics during the PT sources a stochastic gravitational wave background
that can be detected by future experiments. I will show how to construct
a smooth โbounceโ configuration that interpolates between the two phas
es\, allowing for a controlled description of bubble nucleation within 5D
EFT. We will see that the cosmological PT in the minimal models can comple
te only after a large period of supercooling\, potentially resulting in ex
cessive dilution of primordial matter abundances. I will then show how gen
eric modifications of the minimal models can result in a much faster compl
etion of the PT. Finally\, I will discuss the gravitational wave signal pr
oduced by the PT and the implications of the PT for baryogenesis.\n

DESCRIPTION:Title: Multiparticle processes\, large charge and semiclassics\nby
Alexander Monin as part of CERN BSM Forums\n\n\nAbstract\nUnderstanding th
e behavior of a cross section at high enough energies\, when the number of
particles in the final state is large\, is an important and yet unsolved
subject. The difficulty in addressing the question is inapplicability of t
he standard perturbation theory for describing processes with many quanta
even in weakly coupled theories. However\, a certain reorganization (simil
ar to RG improvement) of the perturbative expansion indicates a possibilit
y of a semiclassical description: in other words perturbation theory aroun
d a non-trivial saddle. First\, Iโll present the current state of affair
s with regards to a scalar ๐๐4 theory. And later Iโll show an expl
icit and consistent construction allowing to compute observables like anom
alous dimension etc. for operators with arbitrary large charge in ๐(1)
symmetric scalar field theory at Wilson-Fisher fixed point.\n

oless double-beta decay (0vbb) experiments\naim to discover lepton number
violation in order to shed light on the\nnature of neutrino masses. A non-
zero signal would have profound\nimplications by demonstrating the existen
ce of elementary Majorana\nparticles and possibly pointing towards a solut
ion of matter-antimatter\nasymmetry in the universe. However\, the interpr
etation of the\nexperimental signal (or lack thereof) requires care as com
plicated\nhadronic and nuclear input is required to connect the experiment
al data\nto a fundamental description of lepton-number violation. In this
talk\, I\nuse effective field theories to connect low-energy measurements
to the\nfundamental lepton-number-violating source. In particular\, I will
argue\nthat interpretation of neutrinoless double beta decay in terms of
light Majorana\nneutrinos is more complicated than normally considered.\n

DESCRIPTION:Title: Scattering Amplitudes for Monopoles: Pairwise Little Group and P
airwise Helicity\nby Ofri Telem as part of CERN BSM Forums\n\n\nAbstra
ct\nOn-shell methods are particularly suited for exploring the scattering
of electrically and magnetically charged objects\, for which there is no l
ocal and Lorentz invariant Lagrangian description. In this paper we show h
ow to construct a Lorentz-invariant S-matrix for the scattering of electri
cally and magnetically charged particles\, without ever having to refer to
a Dirac string. A key ingredient is a revision of our fundamental underst
anding of multi-particle representations of the Poincarรฉ group. Surprisin
gly\, the asymptotic states for electric-magnetic scattering transform wit
h an additional little group phase\, associated with pairs of electrically
and magnetically charged particles. The corresponding โpairwise helicit
yโ is identified with the quantized โcross productโ of charges\, e1g
2 โ e2g1\, for every charge-monopole pair\, and represents the extra ang
ular momentum stored in the asymptotic electromagnetic field. We define a
new kind of pairwise spinor-helicity variable\, which serves as an additio
nal building block for electric-magnetic scattering amplitudes. We then co
nstruct the most general 3-point S-matrix elements\, as well as the full p
artial wave decomposition for the 2 โ 2 fermion-monopole S-matrix. In pa
rticular\, we derive the famous helicity flip in the lowest partial wave a
s a simple consequence of a generalized spin-helicity selection rule\, as
well as the full angular dependence for the higher partial waves. Our cons
truction provides a significant new achievement for the on-shell program\,
succeeding where the Lagrangian description has so far failed.\n

Ferruccio Feruglio as part of CERN BSM Forums\n\n\nAbstract\nIn Effective
Field Theories\, gauge anomalies are expected to be determined by the char
ge assignment of the fermion sector\, as in renormalizable theories. Never
theless\, the mechanism of gauge anomaly cancellation is nontrivial and ha
s direct consequences on the computation of physical quantities. By consid
ering a simple explicit model that mimics the SMEFT properties and include
s a complete set of dimension six operators\, the (candidate) anomaly is e
valuated in the regularized theory. The contribution to the anomaly from t
he non-renormalizable sector can be removed by a local counterterm\, havin
g a direct impact on the computation of scattering amplitudes in perturbat

DESCRIPTION:Title: P not PQ\nby Isabel Garcia Garcia as part of CERN BSM Forum
s\n\n\nAbstract\nParity solutions to the strong CP problem are a compellin
g alternative to approaches based on Peccei-Quinn symmetry\, particularly
given the expected violation of global symmetries in a theory of quantum g
ravity. The most natural of these solutions break parity at a low scale\,
giving rise to a host of experimentally accessible signals. We assess the
status of the simplest parity-based solution in light of LHC data and flav
or constraints\, highlighting the prospects for near-future tests at colli
ders\, tabletop experiments\, and gravitational wave observatories. The or
igin of parity breaking and associated gravitational effects play crucial
roles\, providing new avenues for discovery through EDMs and gravity waves
. These experimental opportunities underline the promise of generalized pa
rity\, rather than Peccei-Quinn symmetry\, as a robust and testable soluti
on to the strong CP problem.\n

DESCRIPTION:Title: A heavy axion/'massless up' from partial compositeness\nby
Rick S. Gupta as part of CERN BSM Forums\n\n\nAbstract\nWe show that QCD i
nstantons can generate large effects at small length scales in the ultravi
olet in standard composite Higgs models that utilise partial compositeness
. This has important implications for possible solutions of the strong CP
problem in these models. First\, we show that in the simplest known UV com
pletions of composite Higgs models\, if an axion is also present\, it can
have a mass much larger than the usual QCD axion. Even more remarkable is
the case where there are no axions\, but the strong CP problem can be solv
ed by generating the up-quark mass entirely from the contribution of insta
ntons thus reviving the massless up-quark solution for these models. In bo
th cases no additional field content is required apart from what is requir
ed to realise partial compositeness.\n

DESCRIPTION:Title: Dark matter capture in Celestial objects: Effect of multi-scatt
ering and light mediator\nby Aritra Gupta as part of CERN BSM Forums\n
\n\nAbstract\nWe revisit dark matter (DM) capture in celestial objects\, i
ncluding the impact of multiple scattering\, and obtain updated constraint
s on the DM-proton cross-section using observations of white dwarfs. Consi
dering a general form for the energy loss distribution in each scattering\
, we derive an exact formula for the capture probability through multiple
scatterings. We employ these results to compute a โdarkโ luminosity (L
DM)\, arising solely from the thermalized annihilation products of the cap
tured dark matter. Demanding that LDM does not exceed the luminosity of th
e white dwarfs in the M4 globular cluster\, we set a bound on the DM-proto
n cross-section\, almost independent of the dark matter mass between 100 G
eV and 1 PeV and mildly weakening beyond. This is a stronger constraint th
an those obtained by direct detection experiments in both large masses (M>
5 TeV) and small mass (M<10 GeV) regimes. For dark matter lighter than 350
MeV\, which is beyond the sensitivity of the present direct detection exp
eriments\, this is the strongest available constraint. Moving further\, we
also generalize the formalism for DM capture in celestial bodies to accou
nt for arbitrary mediator mass\, and update the existing and projected ast
rophysical constraints on DM-nucleon scattering cross-section from observa
tions of neutron stars. We show that the astrophysical constraints on the
DM-nucleon interaction strength\, which were thought to be the most string
ent\, drastically weaken for light mediators and can be completely voided.

DESCRIPTION:Title: New ideas for the axion dark matter program\nby Nick Rodd a
s part of CERN BSM Forums\n\n\nAbstract\nThe coming decade will bring dram
atic improvement in the axion dark matter program as new experimental desi
gns move beyond the proof of principle stage. In this talk I will outline
two new ideas that exploit this experimental progress. The first is to com
bine the results from two or more instruments in order to perform interfer
ometry directly on the dark-matter wave. This technique reveals aspects of
the axion signal that can be invisible to a single detector\, such as the
incident direction of the dark-matter wave. The second is to search for r
elativistic axions in these experiments\, in particular future instruments
like dark-matter radio will be sensitive to axions produced in the early
universe that constitute a residual Cosmic axion Background (CaB). Existin
g searches at\, for instance ADMX\, are not yet sensitive to a cosmic reli
c\, although if relativistic axions are produce in the late universe\, by
for instance dark-matter decaying to axions\, then this is a signal the ex
periments are already sensitive to\, but would miss with existing analyses

Forums\n\n\nAbstract\nWe present a new technique for observing low energy
\nneutrinos with the aim of detecting the cosmic neutrino background\nusin
g ion storage rings. Utilising high energy targets exploits the\nquadratic
increase in the neutrino capture cross section with beam\nenergy\, and wi
th sufficient beam energy\, enables neutrino capture\nthrough inverse-beta
decay processes from a stable initial state. We\nalso show that there exi
st ion systems admitting resonant neutrino\ncapture\, capable of achieving
larger capture cross sections at lower\nbeam energies than their non-reso
nant counterparts. We calculate the\nneutrino capture rate and the optimal
experimental runtime for a range\nof different resonant processes and tar
get ions and we demonstrate that\nthe resonant capture experiment can be p
erformed with beam energies as\nlow as O(10TeV) per target nucleon. Unfort
unately\, none of the ion\nsystems discussed here can provide sufficient s
tatistics to discover\nthe cosmic neutrino background with current technol
ogy. We address the\nchallenges associated with realising this experiment
in the future\,\ntaking into account the uncertainty in the beam and neutr
ino momentum\ndistributions\, synchrotron radiation\, as well as the beam

DESCRIPTION:Title: Mergers as a Probe of Particle Dark Matter\nby ANUPAM RAY a
s part of CERN BSM Forums\n\n\nAbstract\nUnusual masses of the black holes
being discovered by gravitational wave experiments pose fundamental quest
ions about the origin of these black holes. More interestingly\, black hol
es with masses smaller than the Chandrasekhar limit (~1.4 solar mass)? are
essentially impossible to produce through any standard stellar evolution.
Black holes of primordial origin\, with fine-tuned parameters and with no
well-established formation mechanisms\, are the most discussed explanatio
n of these objects. In this talk\, I will discuss a simple and elegant pro
duction channel of sub-Chandrasekhar mass non-primordial black holes. Part
icle dark matter with no antiparticle counterpart\, owing to their interac
tion with stellar nuclei\, can catastrophically accumulate inside compact
stars and eventually transmute them to sub-Chandrasekhar mass black holes.
Our recent work points out several avenues to test the transmuted origin
of low mass black holes\, and demonstrates that binary merger rates at hig
h redshift are distinctively different for primordial and transmuted black
holes. Measurement of these binary merger rates by the imminent gravitati
onal wave detectors can conclusively determine the origin of low mass blac
k holes.\n

odels which are can simultaneously explain the neutrino mixings and flavor

๐โฒ\, requires additional singlet scalar for neutrino mixings and an a

of symmetries wherein all generations of quarks are necessarily charged\,
rendering collider constraints to be stringent. We show all our models wit
h the assumption of CKM-like mixings are ruled out from the current data.
Introduction of a single source parameter for non-minimal mixings allows f

DESCRIPTION:Title: Adaptive Mesh Refinement Simulations of Post-Inflationary Axion
Misalignment\nby Joshua Foster as part of CERN BSM Forums\n\n\nAbstra
ct\nAxions are hypothetical particles that may explain the observed dark m
atter (DM) density and the non-observation of a neutron electric dipole mo
ment. An increasing number of axion laboratory searches are underway world
wide\, but these efforts are made difficult by the fact that the axion mas
s is largely unconstrained. If the axion is generated after inflation\, a
unique mass gives rise to the observed DM abundance\; due to nonlinearitie
s and topological defects known as strings\, computing this mass accuratel
y has been a challenge for four decades. Recent works using large static l
attice simulations have led to largely disparate predictions for the axion
mass\, spanning the range from 25 microelectronvolts to over 500 microele
ctronvolts. However\, static lattices are intrinsically limited for studie
s of axion cosmology\, which requires both large simulation volumes and go
od spatial resolution of strings to accurately capture the relevant physic
s. As I will show\, simulations using adaptive mesh refinement\, a techniq
ue for solving systems of partial differential equations on a dynamic non-
uniform lattice\, are better suited for this context since only the string
cores require high spatial resolution. Using dedicated AMR simulations\,
we achieve an over three-order-of-magnitude leap in dynamic range and prov
ide evidence that axion strings radiate their energy with a scale-invarian
t spectrum\, leading to a mass prediction in the range (40\,180) microelec
tronvolts.\n

aftsis as part of CERN BSM Forums\n\n\nAbstract\nFor more than half a cent
ury\, covariant and differential geometric methods have been playing a cen
tral role in the development of Quantum Field Theory (QFT). After a brief
historic overview of the major scientific achievements using these method
s\, I will focus on the covariant and differential geometric formalism ori
ginally proposed by Vilkovisky and DeWitt (VDW). I will discuss recent de
velopments made in addressing the uniqueness of the path-integral measure
of the VDW effective action\, and so address the problem of quantum frame
dependence in cosmologically relevant scalar-tensor theories beyond the cl
assical approximation. I will then turn my attention to a long-standing p
roblem concerning the obstacles that the VDW formalism is facing from its
original conception in describing generic QFTs that include fermions. I wi
ll show how in addition to bosons the VDW effective action can be extended
to supermanifolds to include fermions. The so-extended formulation appea
rs to be very promising for a complete geometrisation of realistic theorie
s of micro-cosmos\, such as the Standard Model and its gravitational secto

DESCRIPTION:Title: The NASDUCK collaboration: using quantum magnetometers to look
for ultralight dark matter\nby Itay Bloch as part of CERN BSM Forums\n
\n\nAbstract\nWhen DM bosons have an ultra-light mass\, they can act as a
classical\, coherent field. In many cases\, and specifically in some ALP m
odels\, this field has magnetic properties\, and it can therefore be measu
red by quantum magnetometers. The Noble and Alkali Spin Detectors for Ultr
alight Coherent darK matter (NASDUCK) collaboration\, was formed last year
in order to measure such DM. Recently\, the collaboration released its fi
rst results from the "NASDUCK-Floquet" experiment\, which looks for DM rou
ghly in the femto to pico eV mass range. The new experiment places the mos
t stringent terrestrial constraints to date on ultra-light axion-like part
icles coupled to neutrons. The constraints are comparable to those from st
ellar cooling\, providing a complementary probe. In my talk I will discuss
the theory behind the NASDUCK-Floquet experiment. I will also discuss fut
ure prospects of the NASDUCK collaboration\, and some of our planned exper
iments.\n

DESCRIPTION:Title: Confinement and Chiral Symmetry Breaking in Near-SUSY Theories<
/a>\nby Ofri Telem as part of CERN BSM Forums\n\n\nAbstract\nThe study of
non-supersymmetric\, strongly coupled gauge theories is notoriously hard\,
and exact results are scarce. In this talk\, I present a new way to study
the vacua of near-supersymmetric theories by perturbing their supersymmet
ric versions with Anomaly Mediated Supersymmetry Breaking (AMSB). Thanks t
o the UV-insensitivity of AMSB\, SUSY results can be perturbed with no amb
iguities\, even when applied to composite fields. Using our method\, we an
alyze the phases of ๐๐(๐) gauge theory with flavors. The abelian
Coulomb and free magnetic phases do not survive supersymmetry breaking and
collapse to a confining phase\, providing one of the first demonstrations
of true confinement with chiral symmetry breaking in a non-supersymmetric
vacuum. Our results are exact in the small SUSY breaking limit\, and we b
riefly discuss the prospects of extrapolating them to large SUSY breaking.

y\nby Juri Smirnov as part of CERN BSM Forums\n\n\nAbstract\nI will di
scuss a detailed study of the confinement phase transition in a dark sect
or with a SU (N ) gauge group and a single generation of dark heavy quark.
We focus on heavy enough quarks such that their abundance freezes out bef
ore the phase transition and the phase transition is of first-order. We fi
nd that during this phase transition the quarks are trapped inside contrac
ting pockets of the deconfined phase and are compressed enough to interact
at a significant rate\, giving rise to a second stage of annihilation tha
t can dramatically change the resulting dark matter abundance. As a result
\, the dark matter can be heavier than the often-quoted unitarity bound of
โผ 100 TeV.\n\nFinally I will show a concrete example where the link bet
ween the dark sector and the standard model is facilitated by a simple Z

part of CERN BSM Forums\n\n\nAbstract\nAfter reviewing some key hints and
puzzles from the early universe\, I will introduce recent work with Neil T
urok suggesting a rigid and predictive new approach to addressing them.\n\
nOur universe seems to be dominated by radiation at early times\, and posi
tive vacuum energy at late times. Taking the symmetry and analyticity pro
perties of such a universe seriously suggests a picture in which spacetime
has two sheets\, exchanged by a symmetry that\, in turn\, selects a prefe
rred (CPT-symmetric) vacuum state for the quantum fields that live on the
spacetime. In this picture\, the Big Bang may be regarded as a kind of mi
rror. \n\nI will explain how this line of thought suggests new explanatio
ns for a number of observed properties of the universe\, including: its ho
mogeneity\, isotropy and flatness\; the arrow of time\; several properties
of the primordial perturbations\; the nature of dark matter (which\, in t
his picture\, is a right-handed neutrino\, radiated from the Big Bang like
Hawking radiation from a black hole)\; and even the existence of three ge
nerations of standard model fermions. I will also mention some observatio
nal predictions that will be tested in the coming decade\, and some key op
en questions.\n

DESCRIPTION:Title: Primordial Black Holes from Multifield Inflation with Non-minim
al Couplings\nby Sarah Geller as part of CERN BSM Forums\n\n\nAbstract
\nPrimordial Black Holes (PBHs)\, first postulated more than half a centur
y ago\, remain an active and fascinating area of research and provide an e
xciting prospect for accounting for Dark Matter. In this talk I will discu
ss the possibilities for production of PBHs near to Dark Matter mass scale
s from realistic multi-field inflation models that arise naturally from su
pergravity. These models fit neatly within the current status of inflation
ary models as constrained by CMB observations\; they behave effectively as
a single-field models for much of their evolution\, and the isocurvature
modes remain heavy throughout. Moreover\, such models yield efficient post
-inflation reheating with N_reh ~ O(1) e-folds after the end of inflation.
I will demonstrate how our two-field model in particular gives rise to in
flationary dynamics that yield predictions for observables in close agreem
ent with recent empirical data\, such as the spectral index and ratio of p
ower spectra for tensor to scalar perturbations. As has been noted in prev
ious studies of PBH formation resulting from a period of ultra slow-roll i
nflation\, we found that at least one dimensionless parameter must be high
ly fine-tuned\, but I will show that we nonetheless find such models yield
accurate predictions for a significant number of observable quantities us
ing a smaller number of free parameters.\n

DESCRIPTION:Title: Domain walls seeding the electroweak phase transition\nby S
imone Blasi as part of CERN BSM Forums\n\n\nAbstract\nTopological defects
can act as local impurities that seed cosmological phase transitions. We w
ill focus on domain walls and discuss their impact on the electroweak phas
e transition in the minimal extension of the SM including a scalar singlet
(xSM)\, odd under a Z_2 symmetry. When the transition is two-step\, the e
arly breaking of the Z_2 implies the formation of domain walls\, which can
then act as seeds for the second and final step. The rate of the seeded p
hase transition can be evaluated within a 3d theory on the domain wall sur
face\, and it is generically faster than the standard homogeneous tunnelin
g. We will comment on the phenomenological implications of this type of tr
ansition.\n

DESCRIPTION:Title: Positivity and the Topography of the SMEFT\nby Nicholas Lle
wellyn Rodd as part of CERN BSM Forums\n\n\nAbstract\nIf the UV completion
of the Standard Model (SM) is unitary\, local\, and causal\, then a rigid
structure emerges in the IR description of the physics provided by the SM
EFT. In this talk I will outline how these restrictions emerge\, describe
how they apply to the SMEFT\, and mention the experimental implications\,
including for existing collider searches. The constraints require the posi
tivity of various SMEFT Wilson coefficients\, but also require a deep conn
ection between effects that conserve and violate flavor and CP in the theo
ry. I will present the sharp statements that can be made at dimension eigh
t\, but also detail what additional assumptions are required to extend the
results to dimension six.\n

DESCRIPTION:Title: Axion couplings in Grand Unified Theories\nby Mario Reig as
part of CERN BSM Forums\n\n\nAbstract\nIn this talk (based on 2206.07053)
I discuss axion couplings to gauge bosons in Grand Unified Theories where
the Standard Model is embedded in a simple 4D gauge group. The topologica
l nature of these couplings allows them to be matched from the UV to the I
R\, and the ratio of the anomaly with photons and gluons for any axion is
fixed by unification. I will show that this implies that there is a single
axion\, the QCD axion\, with an anomalous coupling to photons. Other ligh
t axion-like particles can couple to photons by mixing through the QCD axi
on portal and lie to the right of the QCD line prediction in the mass-coup
ling plane. Axions which break the unification relation between gluon and
photon couplings are necessarily charged under the GUT gauge group and bec
ome heavy from perturbative mass contributions. A discovery of an axion to
the left of the QCD line can rule out simple Grand Unified models.\n
