Strange antibaryons as signature of the quark gluon plasma

In the framework of a hydrodynamical model for relativistic nuclear collisions we present a nonequilibrium model for hadronization of a quark gluon plasma that allows to study hadronic signals for quark gluon plasma formation. In particular, we find that the (non-)strange antibaryon to baryon ratios may serve as a signal for a baryon-rich plasma state, as was suggested earlier
