Abstract

We investigate the production of the [Formula Presented] meson and the [Formula Presented] 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, [Formula Presented] and the transverse flow, [Formula Presented] of the initial deconfined phase are strongly correlated: [Formula Presented] GeV, where [Formula Presented] GeV in the Pb+Pb collision at [Formula Presented] When choosing appropriate initial values of [Formula Presented] and [Formula Presented] from the temperature region [Formula Presented] MeV, the measured [Formula Presented] 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 [Formula Presented].
