Issues addressed and main goals of research: The main aim of the research within the theme is the construction of theoretical models and their application to the description of properties of
elementary particles and their interactions. This research includes the following directions of activity.
The development of quantum field theory formalism in gauge and supersymmetric theories. Construction and investigation of the models of particle physics
beyond the Standard Model. Theoretical support of experiments at the Large Hadron Collider on the search of new physics and the study of the
properties of the Higgs boson.
Calculation of radiative corrections to the processes of particle creation within the Standard Model and its extensions. Investigation of neutrino
properties and neutrino oscillations. Investigation of the hadron properties within quantum chromodynamics and phenomenological quark models. Study
of the hadron spin structure with the help of generalized and transverse momentum dependent parton distributions and theoretical support of NICA/SPD
program.
Study of heavy quark properties and exotic hadrons. Lattice simulations for obtaining nonperturbative results in gauge theories. Investigation of dense
hadronic matter and theoretical support of the MPD/NICA program .
Theoretical support of a wide range of current and future experiments at JINR, IHEP, CERN, GSI, JLab and other physics centers.
Expected main results in the current year:
 Angular analysis of rare threebody Bmeson's decays aimed for
studying of the discovery potential for certain New Physics scenarios at
modern and future Bfactories.
The calculation and the analysis of the structure of the highorder
contributions to the RG quantities in SM extensions with additional
scalars.
Completion of the calculation of virtual corrections to the set of
integrals over two, three and fourparticle phasespace in massless QCD.

structure in the form of Elliptic Polylogarithms.
Evaluating a class of twoloop threepoint functions, having inverse
binomial form for the inverse mass expansions, in the terms of Goncharov
polylogariths.
Calculation of the threeloop corrections to the photon and fermion
selfenergy in the framework of the reduced Quantum Electrodynamics.
Study of the critic behavior of 3dimensional QED in the first three
orders of 1/N_{f}expansion.
Investigation of the LandauKhalatnikovFradkin transformation in the
case of the reduced Quantum Electrodynamics.
Exploration of the semianalytic approach for the transverse momentum
dependent parton densities.
 Completion of the analysis of the phenomenological impact of
radiative corrections to QCD Sum Rules for distribution amplitudes of
(pseudo)scalar and (longitudinal and transverse) vector mesons and the
corrections to the pion transition form factor at N ^{2}LO.
Study of the additional contributions of the oscillation terms of the scattering
amplitude at different energies in the elastic protonproton and
protonantiproton scattering.
Lattice Investigations of hadron structure, more specifically spin content
of nucleons and hyperons.
Calculation of
the transition form factors related to the pionnucleon collision with producing the photon and nucleon
and the nucleon gravitational form factor C(t)
within the LightCone Sum Rules approach including NLO(QCD)term and all twist contributions.
Determination of the polarized parton distribution functions and fragmentation functions in hadrons incorporating transverse momentum of the quarks
(BoerMulders, Sivers, Collins) with the use of the experimental data on the difference cross sections and asymmetries in SIDIS
Study of Z(N) symmetry and thermodynamic properties of metastable
states at very high temperature relevant to HeavyIon Collision and
Early Universe Cosmology.

and doubly charmed baryons.

strength of the binding energy .
Calculation of parameters of the hyperfine splitting of the spectral lines of the pure rotational transition in the molecular ion HD+ in order Z^{6}. That will allow to improve
atomic masses of deuteron and proton from comparison with experiment and to achieve a new level of relative precision of 10 ^{11} in testing quantum electrodynamics in the threebody
sector, which is one order of magnitude better than from the previous results.
 Study phase transitions in quark matter at zero
temperature and nonzero isospin density.

confinement/deconfinement critical temperature,

chemical potential and analytically continuation of calculated
transport coefficients to real chemical potential.

in various regimes of hadronic, mixed and quarkgluon phases.
Fluctuations of particle number, charge and chargedtoneutral
particle ratio in a pionenriched gas will be studied in grand canonical
and canonical ensembles including finitesize effects and particle
interactions. The results will be applied to the description of the
nuclear systems produced in heavyion collisions at RHIC and LHC energies.
Application of nonextensive statistics to description of relativistic heavy ion collisions.
The PHSD model will be extended to include meanfield potentials acting
on fermions and bosons. This will allow for a quantitive comparison
of various relativistic meanfield models in application to heavyion
collisions.
Particle flow pattern (directed flow) and vorticity of a medium
produced in nucleus collisions at NICA energies will be investigated
within the threefluid hydrodynamics approach. The problems of
initial thermalization and light fragment production at NICA energies
will be considered.

fulfilling constraints from Lattice QCD thermodynamics and
compact star astrophysics. Extraction of properties of the lowtemperature, highdensity equation of state from phenomenology of compact stars, their
mergers and supernova explosions; implications for the existence
of a critical endpoint in the QCD phase diagram.
