ly effective field theory where a compact and rotating object is modelled
by a massive\nhigher-spin particle interacting with the gravitational fiel
d. Kerr black holes were found to feature the most simple interaction\nwit
hin this paradigm\, which gives a hope to find the complete theory describ
ing dynamics thereof without any input from numerical and other approaches
. I will present the recent progress in this direction.\n\nhttps://indico.

DESCRIPTION:Speakers: Mohamed Arbab (Qassim University and Khartoum Univer
sity)\nThese fields scale as\, $\\tilde\\phi (\\psi)=\\Omega^\\xi\\\,\\phi
(\\psi)$ and the metric tensor as $\\tilde{g}_{\\mu\\nu}=\\Omega^2\\\,g_{\
\mu\\nu}$\, where $\\Omega$ and $\\xi$ are called the conformal factor and
wight\, respectively. The conformal mass in Klein-Gordon mass ($\\tilde m
$) is related to original scalar mass\, ($m$) by $\\tilde{m}=\\Omega^{-1}
\\\,m$\\\,. Moreover\, the Klein-Gordon equation in the conformal's frame
reduces to the quantum Telegraph equation of a particle whose mass is giv
en by\, $M=(\\xi+1)\\\,m$\, in Minkowski's frame. The conformal wave equa
tion in 2 dimensions with $\\xi=1$ yields the quantum Telegraph equation w
ith a mass. We have found that the conformal wave equation in 2 dimensions
yields the Dirac equation for $\\xi=\\pm\\\,i$ in flat space. In 4 dimen
sions the mass of the conformal spinor field scales as $\\tilde{m}=\\Omega
^{-2}m$. The spinor charge ($q$) is influenced by the conformal transforma
tion and becomes $Q_c=q\\xi/(\\xi+\\frac{3}{2})\\\,$. The conformal factor
for a spinor field is found to be equal to the phase factor of the spinor
field. Moreover\, the conformal transformation preserves the probabilit
y of the spinor particle. There exists a certain conformal transformation
that transforms the Klein-Gordon equation into the Dirac equation. An Ahar
onov- Bohm-like effect is found to occur due to a conformal transformation
of the spinor field. Breaking of conformal invariance is found to give r
ise to a mass of the particle that is tantamount to the Higgs mechanism.\n

DESCRIPTION:Speakers: Yury Pokrovsky (NRC KI\, Moscow)\nIn order to find o
bservable indications for Dark Matter (DM) some possible forms of DM from
DM particles (WIMP) to DM planets in the solar system are considered. In p
articular\, a compact DM planet on a specific orbit in the solar system is
predicted to be a trigger for the solar dynamo with the 11-year cyclic ac
tivity of the Sun. Moreover\, gravitational interaction of this compact DM
planet with the Sun and other planets of the solar system (especially wit
h Mercury\, Venus\, Earth\, Mars\, and Jupiter) leads to explanation of th
e Maunder minimum and other long-time variations of the solar cycle maxima
. This so accurately defines trajectory of the compact DM planet as to ope
n a possibility to observe this compact DM planet in future due to a speci
fic lensing of the light from some stars at predicted moments of the time.

DESCRIPTION:Speakers: Philip Mannheim (Department of Physics\, University
of Connecticut\, Storrs)\nSecond-order-derivative plus fourth-order-deriva
tive gravity is the ultraviolet completion of second-order-derivative quan
tum Einstein gravity. While it achieves renormalizability through states o
f negative Dirac norm\, the unitarity violation that this would entail ca
n be postponed to Planck energies. As we show in this paper the theory has
a different problem\, one that occurs at all energy scales\, namely that
the Dirac norm of the vacuum of the theory is not finite. To establish thi
s we present a procedure for determining the norm of the vacuum in any qua
ntum field theory. With the Dirac norm of the vacuum of the second-order-d
erivative plus fourth-order-derivative theory not being finite\, the Feynm
an rules that are used to establish renormalizability are not valid\, as i
s the assumption that the theory can be used as an effective theory at ene
rgies well below the Planck scale. This lack of finiteness is also manifes
ted in the fact that the Minkowski path integral for the theory is diverg
ent. Because the vacuum Dirac norm is not finite\, the Hamiltonian of the
theory is not Hermitian. However\, it turns out to be $PT$ symmetric. And
when one continues the theory into the complex plane and uses the $PT$ sym
metry inner product\, viz. the overlap of the left-eigenstate of the Hami
ltonian with its right-eigenstate\, one then finds that for the vacuum thi
s norm is both finite and positive\, the Feynman rules now are valid\, the
Minkowski path integral now is well behaved\, and the theory now can serv
e as a low energy effective theory. Consequently\, the theory can now be o
ffered as a fully consistent\, unitary and renormalizable theory of quantu
m gravity.\n\nhttps://indico.ihep.su/event/725/contributions/586/

DESCRIPTION:Speakers: Alexander Kvinikhidze (A. Razmadze Mathematical Inst
itute of the Tbilisi State niversity)\nWe present exact yet practical cova
riant equations of quantum field theory describing a tetraquark in terms o
f a mix of four-quark and two-quark states. A feature of our approach is t
hat it avoids the overcounting problems that usually plague quantum field
theory formulations of few-body covariant equations (the only exception be
ing the two-body Bethe-Salpeter equation).\n Although the model chosen in
the current work describes the four-quark dynamics in terms of meson-meso
n and diquark-antidiquark states\, the derived equations have a form that
is exact\, as all corrections due to the use of a particular model are tak
en into account through the use of a well-defined special four-point ampli
tude $\\Delta$ entering the equations. The equations are in agreement with
those obtained previously by consideration of disconnected interactions [
Phys.Rev.D 90 (2014) 4\, 045042]\; however\, despite being more general\,
they have been derived here in a much simpler and more transparent way.\nA
s an example of the universality of our formulation we show\, that it is a
ble to unify seemingly unrelated models of the tetraquark\, like\, for exa
mple\, the model of the Moscow group [Universe 7\, 94 (2021)] and the coup
led channel\n model of the Giessen group [Phys. Lett. B 718\, 545 (2012)].

rediscovered in recent publications by several groups. The predicted log-
normal mass spectrum of PBHs very well agrees with the data. Our other pre

by the data. It is argued that the cosmological dark matter may fully con

dern Phys.\; Minsk\, Inst. Nucl. Problems)\nAn axion is a hypothetical par
ticle being a quant of pseudoscalar field. It has been originally postulat
ed by Peccei and Quinn in 1977 to resolve the strong CP problem in QCD. If
axions exist\, they are of interest as a possible component of cold dark
matter. The axion–photon coupling distorts the electromagnetic field and
leads to the inverse Primakoff effect which can be observed with haloscop
es. CP-noninvariance of the axion–gluon coupling results in an appearanc
e of oscillating nucleon EDMs which are proportional to the axion field. A
xions manifest themselves in direct interactions with particles (so-called
axion wind effect). We rigorously determine the relativistic spin dynamic
s defined by the pseudoscalar field of dark matter axions. We also show th
at the distortion of the electromagnetic field leads to effective magnetic
charges and EDMs of leptons and effective electric charges of magnetic mo
nopoles (the Witten effect). Axion-like dark matter interacts like the axi
on.\n\nInformation on the subject:\n\nA. J. Silenko\, Relativistic spin dy

DESCRIPTION:Speakers: Mikhail Volkov (Institute Denis Poisson\, Universit

black holes in the Einstein-Weinberg-Salam theory. These black holes are
static and axially symmetric\, they carry a magnetic charge and support no
n-linear Yang-Mills and Higgs fields outside the event horizon. Depending
on the value of the magnetic charge\, their mass and size vary from Planck
values up to values typical for planetary mass black holes. Close to the
horizon the electroweak symmetry is restored\nand geometry is Reissner-Nor
dstrom-de Sitter. The non-linear fields form an "electroweak corona" locat
ed far away from the horizon in the region where the geometry is almost fl
at. These solutions provide the first example of hairy black holes in a ge
nuinely physical theory.\n\nhttps://indico.ihep.su/event/725/contributions

natural product of the complete gravitational collapse of matter and today
we have a body of observational evidence supporting the existence of thes

he center of black holes there are spacetime singularities\, where predict
ability is lost and standard physics breaks down. It is widely believed th
at spacetime singularities are a symptom of the limitations of general rel
ativity and must be solved within a theory of quantum gravity. Since we do
not have yet any mature and reliable candidate for a quantum gravity theo
ry\, researchers have studied toy-models of singularity-free black holes a
nd of singularity-free gravitational collapses in order to explore possibl

vity\, a general theory of relativity that offers a more parsimonious appr
oach compared to general relativity when integrated within a quantum field
theory framework. Requiring only two universal dimensionful parameters in
stead of three\, entangled relativity retains the key components of genera
l relativity\, including a four-dimensional spacetime manifold\, a metric
tensor representing the mechanical properties of space\, inertia\, and gra
vitation\, and matter fields generating curvature. The term "entangled" do
es not directly refer to quantum entanglement but rather emphasizes that m
atter fields and gravity are intrinsically intertwined and cannot be treat
ed separately at the level of the formulation of the theory. Entangled rel
ativity converges toward\, or reduces to\, general relativity in most case
s but predicts a variable quantum of action (ħ) in response to gravitatio
nal phenomena\, particularly in dense environments like neutron stars or t
he early universe. Moreover\, one recovers standard quantum field theory i

traditional cosmology. We argue that in $R^2$-modified gravity superheavy
particles with the interaction strength typical for supersymmetry can be
realistic candidates for the role of the carriers of dark matter. For this
purpose we examined the heating of the universe at the post-inflationary
stage due to decays of the scalaron into several dominant channels and cal
culated the cosmological density of dark matter. The constraints on the ma
sses of DM particles are obtained for different decay modes. Possible obse
rvational manifestations of decays and annihilation of superheavy dark mat
ter particles in the spectrum of high-energy cosmic rays are discussed.\n\

rino-4 experiment (Δm_14^2= 7.3 eV^2 and sin^2〖2θ_14 〗≈0.36) and i
ncreases the confidence level to 5.8σ. Such a sterile neutrino thermalize
s in cosmic plasma\, contributes 5% to the energy density of the Universe\
, and can explain 15-20% of dark matter. It is discussed that the extensio
n of the neutrino model by introducing two more heavy sterile neutrinos in
accordance with the number of types of active neutrinos but with very sma
ll mixing angles to avoid thermalization will make it possible to explain
the large-scale structure of the Universe and bring the contribution of st
erile neutrinos to the dark matter of the Universe to the level of 27%. Th
is approach to the problem of dark matter means that dark matter can be ex
plained in terms of an extended Standard Model with right-handed neutrinos
. An analysis of astrophysical data shows that right-handed neutrinos with
a mass less than 7 keV have not yet been disfavored by direct experiments
. The dynamic process of the origin of dark matter\, consisting of three r
ight-handed neutrinos\, is presented. It is shown that\, based on modern a
strophysical data\, it is impossible to draw a definite conclusion in favo
r of the model of three or four thermalized neutrinos. The influence of le

DESCRIPTION:Speakers: Mikhail Kirsanov (Institute of Nuclear Problems RAS\
, Moscow)\nThermal dark matter models with particle masses below the elect
roweak scale can provide an explanation for the observed relic dark matter
density. This would imply the existence of a new feeble interaction betwe
en the dark and ordinary matter. The main purpose of the NA64 experiment
is a search for sub-GeV dark matter production using the method of missing
energy signature. The searches are performed at the H4 beam line at the C
ERN SPS. This beam is mainly designed to provide 100 GeV electron beam. Th
e analysed statistics corresponds to $9.37\\times10^{11}$ electrons on tar
get (EOT) collected during 2016-2022 runs. The analysis of this statistics
allowed to probe for the first time the well motivated region of paramete
r space of benchmark thermal scalar and fermionic dark matter models. Addi
tional statistics of about $6\\times10^{11}$ was collected in the 2023 ru
n.\n\n In addition to the main 100 GeV electron-beam measurement\, NA64 is
also developing a positron-beam program with several runs at different en
ergies\, to explore the ~ 100 MeV mediator mass range by exploiting LDM pr
oduction via resonant $e^+e^-$ annihilation. An early test run already dem
onstrated the feasibility of the new technique\, allowing to set competiti
ve new limits in a limited mass region despite the much lower accumulated
statistics.\n\n The variant of the NA64 detector for the searches of DM in
the muon beam\, called NA64mu\, has been developed. It uses part of subde
tectors of NA64e and a number of additional subdetectors. The purpose is t
o search for DM coupled only to second and third generations of leptons\,\
nsuggested to explain the (g-2) anomaly and to improve sensitivity in the
region of mediator masses above ~300 MeV.\n\n The program of searches for
Dark Matter in hadron beams with slightly modified NA64 is been developed.
Two test runs have been performed in 2022 and 2023\, the analysis of the
data is now in progress.\n\n NA64 performed and plans also a number other
searches\, such as the search for ALP coupled to gammas\, search for X bos
on decaying to electrons\, search for mu - tau conversion.\n\nY. M. Andree

DESCRIPTION:Speakers: Ilya Shapiro (Universidade Federal de Juiz de Fora\,
MG - Brazil)\nTrace anomaly is one of the most relevant manifestations of
quantum field theory in curved spacetime. It was shown long ago that anom
aly is behind such important applications as Hawking radiation from black
holes and the full version of the Starobinsky inflationary model. In many
cases\, such as using conformal anomaly in black hole physics or exploring
quantum effects on the gravitational waves in curved space\, it is more u
seful and\, in some sense\, necessary to work with effective action. In fo
ur spacetime dimensions (4D) the relevant forms of anomaly-induced action
were derived between 40 and 30 years ago. However\, recently we got some n
ew results in this area\, including integration of anomaly in 6D and the c
ovariant nonlocal forms of the induced action with external scalar fields
and external torsion. On top of that\, now we have a better understanding
of the ambiguities related to local terms\, in both semiclassical theory a
nd conformal quantum gravity. \n\nInformation on the subject: \n\nFab

DESCRIPTION:Speakers: Paul Tappenden (Aix-Marseille University)\nIn his bo
ok Something Deeply Hidden Sean Carroll defends the Everettian concept of
a branching multiverse and in doing so makes some contradictory statements
about the nature of the quantum wavefunction. He writes: “What the Worl
d Is Made Of: a quantum wave function” and “wave functions are superpo
sitions of different possibilities” and “Wave functions may be real bu
t they’re undeniably abstract”. How can our concrete environment be ma
de of something abstract? How can physical objects be constituted by possi
bilities? Many Worlds theory has been haunted by the tension between wave
functions understood as mathematical objects and wavefunction understood a
s physical stuff. I describe a recent approach to this problem which invol
ves applying set theory to physics in a novel way. In the 1960s the logici
an Willard Quine demonstrated that sets need not be thought of as necessar
ily abstract\, non-spatiotemporal objects. A particular type of set can be
construed as concrete. It turns out that Quine’s idea can be built on t
o provide a settheoretic interpretation of quantum indefiniteness. The com
ponents of a superposition can be understood to be its subsets. Each subse
t is a set of objects in the same definite state and different subsets hav
e set-theoretic elements in different definite states. The universal wavef
unction is interpreted as a set of universes\, each of which instances a d
ifferent configuration of particles and/or fields. Unitary evolution is th
e partitioning of wavefunction. The talk will be based on a paper to be fo

ΛCDM standard model of cosmology involves two dark components of the univ
erse\, dark energy\, and dark matter. Whereas dark energy is usually assoc
iated with the (positive) cosmological constant Λ associated with a de Si
tter geometry\, we propose to explain dark matter as a pure QCD effect\, n
amely a gluonic Bose Einstein condensate with the statusof a Cosmic Gluoni
c Background (CGB). This effect is due to the trace anomaly viewed as an e
ffective negative cosmological constant determining an Anti de Sitter geom
etry and accompanying baryonic matter at the hadronization transition from
the quark gluon plasma phase to the colorless hadronic phase. Our approac
h also allows to assume a ratio Dark/Visible equal to 11/2. \n\nInformati

DESCRIPTION:Speakers: Vitaly Vanchurin (Artificial Neural Computing\, Univ

of trainable variables (e.g. bias vector or weight matrix) in an artifici
al neural network can be approximated by Madelung equations if the quantum
phase is identified with the free energy of non-trainable variables (e.g.
state vector of neurons). In addition\, if the number of active neurons c
hanges\, then the free energy is multivalued and the equilibrium dynamics
is better approximated by Schrödinger equation with "Planck's constant" d
etermined by the chemical potential. This shows that quantum mechanics pro
vides a correct statistical description of the dynamics of the grand canon
ical ensemble of neural networks at the learning equilibrium. I will also
briefly discuss a possibility of using the emergent quantumness for buildi
ng an artificial quantum computer and a possibility that the entire univer

DESCRIPTION:Speakers: Leslaw Rachwal (Departamento de Física-Instituto de

We present and discuss well known conditions for ultraviolet finiteness an
d asymptotic safety. The requirements for complete absence of ultraviolet
divergences in quantum field theories and existence of a non-trivial fixed
point for renormalization group flow in the ultraviolet regime are compar
ed based on the example of a six-derivative quantum gravitational theory i
n d=4 spacetime dimensions. Here vanishing of beta functions is equivalent
to the emergence of conformal symmetry on the quantum level. In this mode
l\, it is possible for the first time to have fully UV-finite quantum theo
ry without adding matter or special symmetry\, but by inclusion of additio
nal terms cubic in curvatures. We comment on similarities and some apparen
t differences between the two approaches\, but we show that they are both
compatible with each other. Some features of conformal theory will be pres
ented as well. Finally\, we motivate the claim that actually asymptotic sa
fety needs UV-finite models for providing explicit form of the ultraviolet
limit of Wilsonian effective actions describing special situations at con
formal fixed points.\n\nhttps://indico.ihep.su/event/725/contributions/623

DESCRIPTION:Speakers: Alexander Zakharov (NRC KI\, Alikhanov ITEP\, Moscow
\; JINR\, Dubna)\nAt the initial stage of its development\, the general th
eory of relativity received verification and confirmation in the limit of
a weak gravitational field. However\, with the development of astronomical
observation technologies\, predictions of GRT and in a strong gravitation
al field began to be discussed and confirmed\, such as the profile of the
X-ray iron Kα line (in the case if the emission region is very close to
the event horizon)\, the trajectories of particles and stars near black ho
les and the shapes and sizes of shadows of supermassive black holes in M87
* and Sgr A*. In 2019 the Event Horizon Telescope (EHT) team presented t
he first image reconstruction around the shadow for the supermassive black
hole in M87*. In 2021 the EHT team constrained parameters (“charges”
) of spherical symmetrical metrics of black holes from an allowed interval
for shadow radius. Earlier\, we obtained analytical expressions for the s
hadow radius as a function of charge (including a tidal one) in the case o
f Reissner–Nordström metric. Based on results of the shadow size evalua
tion for M87* done by the EHT team we constrain a tidal charge. We discus
s opportunities to use shadows to test alternative theories of gravity and
alternative theories for galactic centers.\n\nhttps://indico.ihep.su/even

gh statistics data sample of the K+ decays is recorded by the OKA collabor
ation. A missing mass analysis\n\nis performed to search for a light invis
ible pseudoscalar axion-like particle (ALP) in the decay $K^+ \\to \\pi^+
\\pi^0 a$. No signal is observed\, the upper limits for the branching rati
o of the decay are calculated. The 90% confidence level upper limit is cha
nging from $2.5\\times10^{-6}$ to $2\\times10^{-7}$ for the ALP mass from
0 to 200 MeV.\n\nSecond is $K^+ \\to \\mu^+ \\nu g$ decay study and measur
ement of FV - FA :\n\nA new precise measurement of the vector and axial-ve
ctor form factor diff erence FV − FA in the $K^+ \\to \\mu^+ \\nu_{\\mu}
\\gamma$ decay is presented. About 144 K events of $K^+ \\to \\mu^+ \\nu_
{\\mu} \\gamma$ are selected in the OKA experiment.\n\nThe result is FV
− FA = 0.135 ± 0.017(stat) ± 0.024(syst). The result is considered as
preliminary.\n\nThe third is $K^+ \\to \\mu^+ \\nu \\pi^0 g$ decay study.\
n\nThe $K^+ \\to \\pi^0 \\mu^+ \\nu \\gamma (K_{\\mu 3\\gamma})$ is measu
red with OKA setup at the RF-separated 17.7 GeV/c momentum kaon beam of th
e U-70 accelerator. The data corresponds to the flux of $2.62 \\times 10^1
0$ «live» kaons entering the decay volume. More than 900 signal events a
re found with 30-60 MeV energy of the emitted photon in the rest frame of
the decaying kaon. Using $4.48 \\times 10^6$ events of the decay $K^+ \\to
\\pi^0 \\mu^+ \\nu (K_{\\mu 3})$ the branching ratio Br(Kµ3γ)/Br(Kµ3)
is found to be (4.45 ± 0.25(stat)) × 10$^{−4}$. From this value\, usin
g Br($K_{\\mu 3}$) = 3.352% we get Br($K_{\\mu 3\\gamma}$) = (1.492 ± 0.0
85(stat)) × 10$^{−5}$. Our result is preliminary\, with systematic erro

DESCRIPTION:Speakers: Francois-Igor Pris (И.Е. Прись) (Institute of
Philosophy NAS of Belarus\, Minsk)\nWithin the framework of a broadly Wit
tgensteinian approach\, we criticize metaphysical realism\, structural rea
lism and Platonism in philosophy of physics and propose to replace them wi
th what we call “contextual scientific realism” (CSR). According to CS
R\, ontology is sensitive to context. Our view is illustrated with both or
dinary and physical examples. In particular\, we claim that the Higgs boso
n is a contextual object within the framework of the Standard Model and th
e practice of its application\, and that\, in a sense\, the nature of the
gravitational waves depends on the choice of a physical theory to describe
them. A physical theory is interpreted as a Wittgensteinian rule (norm) f
or measuring physical reality within the language games if its application
s. Contextual realism explains the success of our best scientific theories
and (dis)solves the problem of pessimistic induction. It allows one to di
ssolve the so-called “problem of naturalness”. In our view\, it also c
orrects and deepens Porter Williams’ “effective realism”.\n \nInform
