The Equation of State of Nuclear Matter in Heavy Ion Collisions at CERN-SPS Energies from the Viewpoint of Relativistic Hydrodynamics

Abstract

We present refits of single inclusive cross section data of mesons and baryons for central 158 $AGeV$ Pb+Pb collisions measured by the NA44 and NA49 Collaborations. In the theoretical approach we use the relativistic hydrodynamical code HYLANDER-C. We investigate several equations of state in their capability to describe the measured single inclusive momentum distributions. Based on the obtained fits we present results of the calculated Bose-Einstein correlation functions of identical pion pairs and discuss their features in comparison to measurements.
