Application of quantum field theory methods for the description of the interactions of elementary particles and nuclei at high energies.

Theoretical description of the production of elementary particles and light nuclear fragments in high-energy hA-collisions. Feynman graph analysis of the dynamical picture of hadron-nucleus scattering at high energies.

The development of the microscopic (on a quark level) theory of the cumulative phenomena including the nuclear structure functions and particle production at values of the Bjorken-Feynman scaling variable x>1, basing on the possibility to use perturbative QCD methods near the thresholds.

Theoretical investigations of ultrarelativistic heavy ion collisions in connection with A Large Ion Collider Experiment (ALICE) at future Large Hadron Collider (LHC) at CERN. In particular the studies of the long-range correlations between particles produced in the forward and backward hemispheres in nuclear collisions at high energies, as a possible source of information on colour strings fusion phenomenon.
