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.
