In ultrarelativistic nuclear collisions heavy quarks are produced out of thermal equilibrium in the very early stage of the reaction and their thermalization time was expected to be considerably larger than that of light quarks. On the…

We discuss the bulk properties of QGP produced at RHIC obtained at time of hadronization. We argue that hadronization of quark--gluon plasma occurs at a critical pressure of 82 MeV/fm3, obtained for SPS energy range.
Typically the materialization of high energetic transverse partons to hadronic jets is assumed to occur outside the reaction zone in a relativistic heavy ion collision. In contrast, a quantum mechanical estimate yields a time on the order…
