Inclusive processes at high energies are studied in a non-perturbative
approach in QCD using a modified Quark-Gluon String Model. Theoretical and
experimental aspects of diffraction dissociation are especially discussed.
In the calculations of cross sections, the parameters of complex nonlinear
trajectories of Pomeranchuk and Reggeons are used. Particular attention
is paid to elastic and...

Gravitational formfactors describe the (angular) momentum distribution in hadrons as well as their coupling to gravity. The equivalence principle may be extended to be valid separately for quarks and gluons. The small violation of such an extension may be related to the analog of shear viscosity contribution and be a counterpart of its smallness.
Collective effects are reviewed for collisions of various systems – from proton-proton to heavy ion – in wide energy range. Collectivity is one of the crucially important and most essential fea-tures in reactions with subatomic particles due to strong interaction. As consequence, a study of collective behavior in multiparticle production processes provides one of the most sensitive and...

The transition of strong-interaction matter from the hadronic phase to the quark-gluon plasma phase is a rapid crossover rather than a true phase transition in nature. A true phase transition in strong-interaction matter is expected to exist only under certain conditions, such as the chiral limit of massless quarks.
In this talk, I will present our recent studies on the true phase transition...
In this report the influence of relativistic rotation on QCD
properties will be considered. I am going to review the results that
were obtained within lattice simulation of QCD. It has become
commonplace to perform such studies in the reference frame rotating
with the system under investigation. In this case there appears the
gravitational field and the problem is reduced to study of QCD in...
After a historical introduction I will review progress in description of the pion degrees of freedom in equilibrium and nonequilibrium nuclear matter. Effects of the softening of the pion mode and pion condensation will be considered. Applications to such nuclear systems as atomic nuclei, neutron stars, heavy-ion collisions, and hypothetical nuclear systems will be...
I will compare the main confinement mechanisms in QCD, confinement by magnetic monopoles and by quantised magnetic flux tubes, vortices. Then, I will concentrate on problems with the detection of vortices. A further interesting question concerns the relation to the spontaneous breaking of chiral symmetry.

The most valuable task for high-energy physics at future colliders is the study of the Standard Model features in detail. That is required to resolve crucial problems of this model including the origin of the spontaneous symmetry breaking, the metastability of the Higgs boson vacuum, the symmetry and mass hierarchy of three fermion generations, etc. High statistics and advanced experimental...

Odderon is the C-odd amplitude which does not die out (or die very slowly) with energy. We consider the constrains on the Odderon properties and the
perturbative QCD odderon given at the lowest $\alpha_s$ order by the three gluon exchange. Then we discuss the experimental indications for the odderon
contribution to high energy proton-proton elastic scattering and some other processes in which...
The soft and hard QCD processes are analyzed by ALICE, ATLAS and CMS experiments using samples of proton-proton and AA collisions collected by the LHC at different energies. Measurements of jet production rates, jet properties, particle multiplicity, particle momentum spectra and correlations are presented.
The results are compared to predictions of theoretical models at leading- and...

The rare decay process of the Higgs boson into a pair of J/Ψ and ϒ particles is studied within the perturbative Standard Model and the relativistic quark model. We study also the processes of single and paired production of lepton bound states (positronium, dimuonium, ditauonium) within the framework of the relativistic approach we are developing [1-5]. The relativistic corrections connected...
The shear-like contributions to energy-momentum tensors appearing in the definitions of hadronic matrix elements are considered. Their extraction from sum rule for various parton distributions is analyzed. The counterparts of the viscosity smallness manifested in holographic QCD are discussed.
