Blast--wave analysis of strange particle $m_{\rm T}$ spectra in Pb--Pb collisions at the SPS

Blast--wave analysis of strange particle $m_{\rm T}$ spectra in Pb--Pb collisions at the SPS

The transverse mass spectra of high statistics, high purity samples of $K^{0}_{S}, \Lambda, \Xi and \Omega$ particles produced in Pb–Pb collisions at SPS energy have been studied in the framework of the blast-wave model. The dependence of the freezeout parameters on particle species and event centra...

Zusammenfassung:The transverse mass spectra of high statistics, high purity samples of $K^{0}_{S}, \Lambda, \Xi and \Omega$ particles produced in Pb–Pb collisions at SPS energy have been studied in the framework of the blast-wave model. The dependence of the freezeout parameters on particle species and event centrality is discussed. Results at 40 A GeV/c are presented here for the first time
