STRANGE PARTICLES FREEZE-OUT CONDITIONS FROM A NEW HADRONIC EQUATION OF STATE

We propose a thermodynamically consistent equation of state (EOS) for a hot and dense handron gas (HG) incorporating the hard-core finite-si ze correction for baryons which result in a Van-der Waals excluded vol ume effect. We develop a complete description within a thermal hadron gas model to determine the production of strange particles in relativi stic nucleus-nucleus collisions and calculate the strange particle rat ios as function of baryon chemical potential mu(B) and temperature T. The results are compared with other existing thermodynamically consist ent EOS. Furthermore we extract the thermal freeze-out parameters for different strange particles using the latest data obtained by the CERN experiments.
