Introduction to physics of relativistic nucleus-nucleus collisions.
An outline of the fundamentals of relativistic nuleus-nucleus collisions: their purpose, methods of its realization and the physical basis for this. The main features of accelerators and detectors. Description of the observed quantities and methods of their measurement. Among them: the multiplicity of particles at...
Property of hadrons. Conserved charges -- baryonic number, strangeness, electric charge. Chemical equilibrium and chemical potentials. Resonances. Chemical freeze-out and hadron multiplicities in nucleus-nucleus collisions. Canonical ensembles for small systems.
Quark gluon plasma. Bag model. Lattice QCD results. Experimental signatures.
The models of relativistic nuclear-nuclear collisions: statistical, as historically the first, and currently used - thermal, hydrodynamic, kinetic, and others will be described. Significant attention will be paid to the hydrodynamic approach to nuclear collisions modeling as the basis of all modern models. The pioneering analytical model - the hydrodynamic Landau model, as well as the more...
We investigate nucleon production in proton-nucleus collisions outside the kinematical boundary of proton-nucleon reactions.
The maximal energy of protons emitted in the backward direction is estimated.
We suggest that cumulative nucleons are produced by heavy baryonic resonances created in p+A collisions due to successive collisions with nuclear nucleons.
We also compare theoretical...

- Introduction to the hydrokinetic approach.
The modern integrated hydrokinetic approach to A+A collisions will be presented. It includes a complete spatiotemporal picture of nucleus-nucleus collisions :
1) the formation of an initial nonthermal state of matter characterized by a certain distribution of the ultrahigh energy density;
2) a description of the process of thermalization of...
4.The soft physics observables and the space-time picture of nuclear collisions in the integrated hydrokinetic model.
It will be demonstrated how using the integrated hydrokinetic model and the soft physics observables from Large Hadron Collider (LHC) and Relativistic Heavy Ion Collider (RHIC) , to restore space-time picture of the matter evolution in ultrarelativistic nucleus-nucleus...
