Centrality Dependence of the Expansion Dynamics in Pb-pb Collisions at 158 a Gev/c Expansion Dynamics in Pb-pb Collisions 2


Two-particle correlation functions of negatively charged hadrons from Pb-Pb collisions at 158 GeV/c per nucleon have been measured by the WA97 experiment at the CERN SPS. A Coulomb correction procedure that assumes an expanding source has been implemented. Within the framework of an expanding thermalized source model the size and dynamical state of the… (More)
