Abstract / Resumo
Short range particle repulsion is proven to be rather important property of the hadronic and nuclear matter equations of state. Excluded volume effects play a significant role in the description of the experimental data measured in nuclear-nuclear collisions. Modelling of the compact astrophysical objects interior also require accounting for the hadronic excluded volume which is necessary for thermodynamically consistent description of the statistical phase transitions expected at high baryonic densities typical for neutron stars. Novel approach based on the analysis of the virial expansion is used to derive thermodynamically consistent equation of state of strongly interacting matter. The mean-filed interactions are also incorporated into this approach.
Applications of the present equation of state to the description of the hadronic multiplicities measured in nuclear-nuclear collisions, to studies of the nuclear matter phase diagram and to modelling of the neutron star interiors are discussed.
