Liquid-gas Phase Transition in Strange Hadronic Matter with Weak Y-Y Interaction

Nuclear Theory 2007-05-23 v1

Abstract

The liquid-gas phase transition in strange hadronic matter is reexamined by using the new parameters about the ΛΛ\Lambda - \Lambda interaction deduced from recent observation of ΛΛ6He^{6}_{\Lambda\Lambda}He double hypernucleus. The extended Furnstahl-Serot-Tang model with nucleons and hyperons is utilized. The binodal surface, the limit pressure, the entropy, the specific heat capacity and the Caloric curves are addressed. We find that the liquid-gas phase transition can occur more easily in strange hadronic matter with weak Y-Y interaction than that of the strong Y-Y interaction.
