Evidence for a high entropy phase in nuclear collisions
J. Letessier, A. Tounsi, U. Heinz +2
We determine the entropy per baryon content of the central reaction region in terms of the charged particle multiplicity. We study the consistency of our findings with recent data…
On Chemical Equilibrium in Nuclear Collisions
F. Becattini, M. Gazdzicki, J. Sollfrank
The data on average hadron multiplicities in central A+A collisions measured at CERN SPS are analysed with the ideal hadron gas model. It is shown that the full chemical equilibriu…
Chemical equilibration of strangeness
Josef Sollfrank
Thermal models are very useful in the understanding of particle production in general and especially in the case of strangeness. We summarize the assumptions which go into a therma…
Initial Conditions in the One-Fluid Hydrodynamical Description of Ultrarelativistic Nuclear Collisions
Josef Sollfrank, Pasi Huovinen, P V Ruuskanen
We present a phenomenological model for the initial conditions needed in a one-fluid hydrodynamical description of ultrarelativistic nuclear collisions at CERN--SPS. The basic ingr…
