Abstract

We investigate the production of the φ meson and the Ω baryon which interact relatively weakly with hot hadronic matter, their spectra thus reflecting the early stage of the heavy ion collisions. Our analysis shows that the hadronization temperature, Thad, and the transverse flow, v0T of the initial deconfined phase are strongly correlated: Thad + a · (v0T)2 = 0.25 GeV, where a = 0.37 GeV in the Pb+Pb collision at 158A GeV/c. When choosing appropriate initial values of Thad and v0T from the temperature region Thad = 175 ± 15 MeV, the measured ρ meson spectra was reproduced surprisingly well by the MICOR model. We have found weak influence of final state hadronic interactions on the transverse hadron spectra at mT - mi>0.3 GeV.
