Study of the transverse mass spectra of strange particles in Pb-Pb collisions at 158 A GeV/c

Abstract : The Na57 experiment has collected high statistics, high purity samples of K$^0_s$ and $\Lambda, \Xi $ and $\Omega$ hyperons produced in Pb-Pb collisions at 158 A GeV/c. In this paper we present a study of the transverse mass spectra of these particles for a sample of events corresponding to the most central 53 $\%$ of the inelastic Pb-Pb cross-section. We analyse the transverse mass distributions in the framework of the blast-wave model for the full sample and, for the first time at the SPS, as a function of the event centrality.
