Analysis of Hadronic Properties at SPS energies from a Statistical Model

Nuclear Theory 2007-05-23 v1

Abstract

Using a statistical model of multiparticle production by Chou, Yang and Yen, which looks similar to the thermal model and is known to account for the single particle distributions in e+^+ e^- collisions, we fit the rapidity and transverse mass spectra of pions and kaons measured in Pb+Pb collisions by NA49 collaboration. This model nicely fits both the rapidity and the transverse mass spectra of each particle species with a few parameters. However, fitting all the particles with a single value of TpT_p is not possible. This analysis shows that the success of the thermal models does not necessarily mean the thermalization of the system in collision.
