Essay

The thesis is devoted to the theoretical study of the space-time structure and the character of the evolution of systems formed in relativistic heavy-ion (nuclear) collisions, to the investigation of the properties of new strongly interacting matter forms (such as quark-gluon plasma) created during the intermediate stages of the collision, and to the analysis of the mechanisms of final hadronic observables formation in the soft physics domain. The research is primarily conducted within the integrated HydroKinetic Model (iHKM) for nucleus-nucleus collisions, which allows for realistic modeling of the evolution of the created system through five successive stages: initial state formation, pre-equilibrium dynamics, hydrodynamic expansion, particlization (conversion of the continuous matter into a system of particles), and the hadronic cascade. The study addresses several topical problems, including the initial conditions for the system’s evolution, the equation of state of quark-gluon matter at the hydrodynamic stage, the analysis of the space-time structure of the created systems, the description of experimental data from modern particle accelerators concerning soft hadronic observables, the role of the collision hadronic stage in the formation of these observables, the problem of sudden versus continuous freeze-out of particle yields and momentum spectra, the estimation of different collision stages’ duration, the analysis of baryon-baryon final-state interactions, and more.
