| Abstract: | Thermodynamical properties of hot and dense nuclear matter are analyzed and compared for different equations of state (EoS). It is argued that the softest point of the equation of state and the strangeness separation on the phase boundary can manifest themselves in observables. The influence of the EoS and the order of the phase transition on the expansion dynamics of nuclear matter and strangeness excitation function is analyzed. It is shown that the bulk properties of the strangeness production in A-A collisions depend only weakly on the particular form of the EoS. The predictions of different models are related with experimental data on strangeness production.Received: 11 August 2003, Published online: 3 December 2003 |
