The purpose of the Project: Development of new theoretical approaches for the correct description of two phase transitions in dense QCD matter formed in collisions of heavy ions; study of the influence of finiteness of the formed systems on the peculiarities of the phase transformations of deconfinement and restoration of chiral symmetry, formulation of experimentally observable signals of these phase transitions and their (three)critical point or points. The main results obtained: The equation of state of hadronic matter is formulated on the basis of generalization of our previously proposed system of equations by including into this system, in addition to pressure and surface tension coefficient, also the curvature coefficient. Modification of the numerical code of the hadron resonant gas model was carried out, as well as general fitting of all available hadron sets is performed to determine the radii of the hard cores of the most common hadrons, i.e. pions, nucleons, Λ-hyperons and kaons. Within the development of the general theory of nuclear matter, an explanation is given for the impossibility of the existence of a stable infinite nuclear matter consisting of α-particles due to the instability of such a hypothetical system with respect to spatial collapse.   Product Description popup.authors Borysyuk Dmytro L Bugaev Kyrylo Oleksiyovych Vityuk Olexander V Grinyuk Borys Ye popup.nrat_date 2022-03-09 Close
