TY - INPR A1 - Spieles, Christian A1 - Stöcker, Horst A1 - Greiner, Carsten T1 - Hadron production in relativistic nuclear collisions : Thermal hadron source or hadronizing quark-gluon plasma? N2 - Measured hadron yields from relativistic nuclear collisions can be equally well understood in two physically distinct models, namely a static thermal hadronic source vs. a time-dependent, nonequilibrium hadronization o a quark-gluon plasma droplet. Due to the time-dependent particle evapora- tion o the hadronic surface in the latter approach the hadron ratios change (by factors of
