【 摘 要 】

The Statistical Hadronization Model can be extended to include hadrons which are produced far away from chemical equilibrium or in an earlier phase of the evolution of a heavy ion collision. The effects of J/ψ production above the critical temperature are explored, with special focus on the mass shift for the thermal dressed mass of the charm quarks in the quark-gluon plasma.
