Abstract
Using the strange-hadron mass spectrum, theμ q/T andμ s/T values obtained from strange particle ratios, we estimate the temperature of the equilibrated primordial state for several nuclear interactions at AGS and SPS. Fitting the systematics forT,μ q and transverse flow velocity we predict their values at RHIC. On the basis of lattice calculations and experimental evidence, we propose the existence of an intermediate phase: the Deconfined Quark Matter (DQM) phase with massive and correlated quarks. We define theμ s = 0 curve as the boundary between the HG and DQM phases for the strange-hadron sector and write an empirical EoS for the latter region. Its distinct characteristic is the negative strange-quark chemical potential. Experimental suggestion forμ s < 0 may have been seen in S+A interactions at 200A GeV.
