Centrality Dependence of Thermal Parameters in Heavy-Ion Collisions at CERN-SPS

Nuclear Theory 2008-11-26 v2 High Energy Physics - Phenomenology

Abstract

The centrality dependence of thermal parameters, characterizing the hadron multiplicities, is determined phenomenologically for lead-on-lead collisions at CERN-SPS for a beam energy of 158 AGeV. The strangeness equilibration factor shows a clear, approximately linear, increase with increasing centrality, while the freeze-out temperature and chemical potential remain constant.
