Strangeness Production in a Chemically Equilibrating Quark-Gluon Plasma

We study the strangeness of a chemically equilibrating quark-gluon plasma at finite baryon density based on the Jüttner distribution of partons. We find that the strangeness production depends obviously on the initial values, and will accelerate with the change of the initial system from a chemically non-equilibrated to an equilibrated system. We also find that the calculated strangeness is very different from the one in the thermodynamic equilibrium system. This study may be helpful to understand the formation of quark-gluon plasma via a chemically non-equilibrated evolution framework.
