Poberezhniuk R. Phase transitions and critical point of strongly interacting matter in nucleus-nucleus collisions

In thesis the qualitative predictions of possible deconfinement signals are obtained. In particular, of signals that are observed in collision energy dependences of strangeness production in proton-proton interactions. As well as of charm production and strongly-intensive fluctuation measures in lead-lead collisions. Also in thesis the phenomenon of limiting temperature in the gas of pions with the van der Waals equation of state is discovered. The behavior of the system in the vicinity of the limiting temperature is compared with the corresponding behavior of hadronic matter with the Hagedorn equation of state. Equations for the fluctuations of nuclons multiplicity in the region of the critical point of nuclear matter with the van der Waals equation of state are obtained.
