Scientific Programme:
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. 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 program NICA. Theoretical support of a wide range of current and future experiments at JINR, IHEP, CERN, GSI, DESY and other physics centers.

Expected main results in 2017:
  • Calculation of ultraviolet divergences in maximally supersymmetric gauge theories in extra dimensions in all orders of perturbation theory.

    Theoretical analysis of SUSY searches at LHC in the framework of the MSSM and the NMSSM based on experimental data from ATLAS and CMS.

    Investigation of the effects due to radiative corrections in Drell-Yan processes after increasing LHC luminosity and beam energy.

    Studies of Q 2-evolution of the average gluon and quark jet multiplicities with the double-logarithm resummation taken into account.

    Investigation of high-energy asymptotics of the structure function F2 and its heavy quark parts.

    Development of the method of incorporation of strong corrections in to physical observables at an arbitrary order of QCD perturbation theory within the dispersive approach.

    Development of a twistor description for form factors and off-shell amplitudes in theories with extended supersymmetry.

    Study and calculation of anomalous dimensions of twist 2 operators in the case of ABJM and orbifold deformations of N=4 SYM within the quantum spectral curve approach.

    Studies of the dark matter problem in the framework of the Standard Model and beyond it, including its supersymmetric generalizations. Building of Minimal Consistent Dark Matter models. Development of the strategy of comparing/mapping of their parameters for results of searches.

  • Extraction of non-OPE QCD short string contributions to annihilation and decay processes using the standard and IR-modified couplings.

    Account for strange quark mass effects in the anomaly sum rules in space-like and time-like regions.

    Calculations for different mechanisms of exclusive Drell-Yan pairs production from NICA to LHC energies.

    Lattice calculations of transverse-momentum dependent distributions and hadron polarizabilities.

    Development of a complementary scheme of processing of low x data for spin-dependent structure functions based on truncated moments used.

  • Calculation of the hadronic light-by-light contributions to the muon anomalous magnetic moment in the leading and next-to-leading orders in the 1/Nc parameter.

    Investigation of meson creation at low energies at electron-positron beams.

    Calculations of widths of tau decays.

    Calculation of the contribution of anomalous quark-gluon chromomagnetic interaction to the single- and double- spin asymmetries for inclusive pion production in high energy proton-proton collisions.

    The glueball/Hybrid spectrum of the Hamiltonian of Dirac-Yang-Mills quantum mechanics of spatially constant fields, which constitutes to the lowest leading order in strong coupling, will be calculated with high precision for both the baby version of SU2 and the real case of SU3, using a systematic variational approach based on an orthonormal basis of trial states which are the exact analytical solutions of the corresponding harmonic oscillator problem.

  • Participation (continuation) in the tmfT Collaboration (finite temperature with twisted mass fermions) aimed at description of the quark-gluon thermodynamics including strange and charmed quarks and consideration of new observables indicating the crossover.

    Study of the phenomenology of topological defects (Z(3) walls and associated strings) with metastable Z(3) domains based on lattice QCD calculations.

    Investigation of the contribution of topological degrees of freedom (monopoles, dyons, vortices) to the properties of strongly interacting quark-gluon plasma.

    Investigation of the influence of the glueballs to the properties of sQGP above the deconfinement temperature in hot/dense nuclear matter.

    Study of the generation of vorticity in heavy-ion collisions and its effect on P-odd correlations of quarks and mesons in the NICA energy range.

    Investigation of the role of color degrees of freedom at the early stage of heavy-ion interactions within the model of Parton Hadron String Dynamics (PHSD), estimation of the intensity of chromoelectric and chromomagnetic fields created in collisions of relativistic heavy ions.

    Investigation of observable manifestations of the nonperturbative gluon fields (domain walls and nontopological solitons) in the collisions of relativistic heavy ions. Study of the influence of electromagnetic fields on the formation of a heterophase mixed phase within the domain model of the QCD vacuum.

    The THESEUS programme will be used to generate events at NICA energies. The research will concern mainly the study of the new EoS and transport coefficients. Study of hybrid EoS (equations of state) based on ab-initio nuclear EoS and non-local PNJL models in a wide range of densities, temperatures and isospin asymmetry, applications in the simulation of heavy-ion collisions and supernova collapse and in compact star phenomenology.
