On separate chemical freeze-outs of hadrons and light (anti)nuclei in high energy nuclear collisions
K. A. Bugaev, B. E. Grinyuk, A. I. Ivanytskyi +9
The multiplicities of light (anti)nuclei were measured recently by the ALICE collaboration in Pb+Pb collisions at the center-of-mass collision energy TeV. Sur…
Neutrino spin oscillations in polarized matter
A. Grigoriev, E. Kupcheva, A. Ternov
We study the neutrino spin oscillations, i.e., neutrino spin precession caused by the neutrino interaction with matter polarized by external magnetic field (or, equivalently, by th…
LHC-friendly minimal freeze-in models
G. Bélanger, N. Desai, A. Goudelis +8
We propose simple freeze-in models where the observed dark matter abundance is explained via the decay of an electrically charged and/or coloured parent particle into Feebly Intera…
Hard-core Radius of Nucleons within the Induced Surface Tension Approach
K. A. Bugaev, A. I. Ivanytskyi, V. V. Sagun +9
In this work we discuss a novel approach to model the hadronic and nuclear matter equations of state using the induced surface tension concept. Since the obtained equations of stat…
Existing and expected manifestations of a new fundamental interaction
L. M. Slad
A number of characteristics of the new fundamental interaction are described. The interaction is carried by a massless pseudoscalar boson and extends to at least the electron neutr…
Are there narrow flavor-exotic tetraquarks in large- QCD?
Wolfgang Lucha, Dmitri Melikhov, Hagop Sazdjian
A salient feature shared by all tetraquark candidates observed in experiment is the absence of flavor-exotic states of the type , with four different quark flavor…
Quadrupole moments of spin-1 systems: the rho meson, the S-wave deuteron and some general constraints
A. F. Krutov, V. E. Troitsky
We costruct the relativistic operator of the quadrupole moment of two-particle composite spin one systems with zero orbital moment of the relative motion and derive explicit analyt…
Strong Isospin Breaking in Heavy-Meson Decay Constants: Employing Borelized QCD Sum Rules in Local-Duality Limit
Wolfgang Lucha, Dmitri Melikhov, Silvano Simula
Applying the QCD sum-rule machinery in the so-called local-duality shape to heavy-light mesons reveals that, as a consequence of the non-zero mass gap between up and down quarks, t…
Associated non-prompt and production at LHC as a test for TMD gluon density
S. P. Baranov, A. V. Lipatov, M. A. Malyshev
We consider the associated production of mesons and muons originating from the -flavored hadron decays and non-prompt double production at the LHC using the -fa…
Exotic Tetraquark Mesons in Large- Limit: an Unexpected Great Surprise
Wolfgang Lucha, Dmitri Melikhov, Hagop Sazdjian
Two-ordinary-meson scattering in large- QCD implies consistency criteria for intermediate-tetraquark contributions. Their fulfilment at -leading order constrains the natu…
Long-distance QCD effects in FCNC decays
Anastasiia Kozachuk, Dmitri Melikhov, Nikolai Nikitin
This presentation reviews the main results of our recent work [A.K., D.M., N.N., Phys. Rev. D97, 053007 (2018)] on rare radiative leptonic decays and $B_{d,s}\t…
Hypothesis about semi-weak interaction and experiments with solar neutrinos. II. Deuteron disintegration by neutral currents
L. M. Slad
The present work provides one more evidence of that the solar neutrino problem has an elegant solution based on the hypothesis about the existence of a new, semi-weak, interaction.…
No- Theorem for Euclidean Massless Correlators
P. A. Baikov, K. G. Chetyrkin
We provide the reader with a (very) short review of recent advances in our understanding of the -dependent terms in massless (Euclidean) 2-point functions as well as in generic…
Compact Exotic Tetraquark Mesons in Large- QCD
Wolfgang Lucha, Dmitri Melikhov, Hagop Sazdjian
We embark on systematic explorations of the behaviour of tetraquark mesons (colour-singlet bound states of two quarks and two antiquarks) in the (idealized) limit of a large number…
Interplay of the LHC and non-LHC Dark Matter searches in the Effective Field Theory approach
Alexander Belyaev, Enrico Bertuzzo, Cristian Caniu Barros +4
We present accurate and up-to-date constraints on the complete set of dimension five and six operators with scalar, fermion and vector Dark Matter (DM). We find limits using LHC mo…
Model independent top quark width measurement using a combination of resonant and non resonant cross sections
Alexey Baskakov, Eduard Boos, Lev Dudko
Though top quark was discovered more than twenty years ago, measurement of its width is still challenging task. Most measurements either have rather low precision or they are done…
Linking infrared and ultraviolet parameters of pion-like states in strongly coupled gauge theories
Sergey Troitsky, Vadim Troitsky
It has been shown previously that in a relativistic constituent-quark model, predictions for the electromagnetic form factor of the pi meson match not only experimental data but al…
Numerical calculation of high-order QED contributions to the electron anomalous magnetic moment
Sergey Volkov
This paper describes a method of numerical evaluating high-order QED contributions to the electron anomalous magnetic moment. The method is based on subtraction of infrared and ult…
Employing RHIC and LHC data to determine TMD gluon density in a proton
N. A. Abdulov, H. Jung, A. V. Lipatov +2
Transverse momentum dependent (TMD) parton distributions in a proton are important in high energy physics from both theoretical and phenomenological points of view. Using the lates…
Evaluating `elliptic' master integrals at special kinematic values: using differential equations and their solutions via expansions near singular points
Roman N. Lee, Alexander V. Smirnov, Vladimir A. Smirnov
This is a sequel of our previous paper where we described an algorithm to find a solution of differential equations for master integrals in the form of an -expansion series with…

S. P. Baranov, A. V. Lipatov
In the framework of perturbative QCD and nonrelativistic bound state formalism, we calculate the production of and mesons at the conditions of the CDF and LHCb experi…
Revisiting nonfactorizable charm-loop effects in exclusive FCNC -decays
Anastasiia Kozachuk, Dmitri Melikhov
We revisit the calculation of nonfactorizable corrections induced by charm-quark loops in exclusive FCNC -decays. For the sake of clarity, we make use of a field theory with sca…

P. A. Baikov, K. G. Chetyrkin
Extending an argument of [Baikov:2010hf] for the case of 5-loop massless propagators we prove a host of new exact model-independent relations between contributions proportional to…
