The aim of the research is to investigate the magnetic field generation mechanisms in the Early Universe in quark-gluon plasma (QGP) and macroscopic parameters of QGP; to study new heavy neutral gauge boson characteristics using the data collected in modern experiments; to develop kinetics of electromagnetic processes in terms of quasiparticles; to develop electrodynamics of emitting continuous media; to investigate Bose-gas with quasiparticles in hydrodynamic state: to study supercritical phase transitions in matter. The obtained results substantially contribute to high-temperature field theory. New properties of gluon spectra were studied, allowing for a more precise and consistent description of QGP in the deconfinement phase. The results concerning the Z' boson can be used for analysis of experimental data collected on the Tevatron and LHC. The results of investigation of electromagnetic field kinetics in plasma and in emitting media lead to novel of studying such systems and also allow to establish relation woth traditional approaches of plasma and quantum optics. Extension of the Gross-Pitaevskii theory to a case of quasiparticles in a hydrodynamic state with account for dissipation processes increases possibilities to verify theory predictions in experiments. A new approach for description hydrodynamic processes in superfluid Bose-liquid leads to certain simplifications in description of such systems using common fluid hydrodynamics. The results on thermodynamic stability investigation allow to solve several uncertainties that are present in critical state thermodynamics, and also to relate fluctuations in supercritical region to vibration anharmonicity in solids. The obtained results are new and represent substantial contribution to theory of elementary particles, quantum field theory at extreme external conditions, thermodynamic stability theory, continuous media electrodynamics, Bose-gas kinetics in presence of condensate and Bogolyubov's method for non-equilibrium processes analysis. The scientific credibility and world class of the results are were proven at international conferences and acknowledged by referees of international journals in which the results are published. The results of the research project can be implemented in leading Ukrainian and foreign scientific institutions.
