The phase transition of chiral symmetry restoration in strange hadronic matter is studied in the chiral SU(3) quark mean field model. When the baryon density is larger than a critical density ρ c , the minimal energy density of the system occurs at the point where the effective masses of nucleon, Λ or Ξ drop to zero. The physical quantities change discontinuously at this density and the system will be in the phase of chiral symmetry restoration. A rich phase structure of strange hadronic matter with different strangeness fraction f s is obtained.

“…In studying hadronic matter, we proposed a chiral SU(3) quark mean field model. This chiral quark model was applied to investigate the properties of strange hadronic matter and multi-strange hadronic systems [31,32]. In this paper, we want to use this model to discuss the stability of strange quark matter.…”

We apply the chiral SU(3) quark mean field model to investigate strange quark matter. The stability of strange quark matter with different strangeness fraction is studied. The interaction between quarks and vector mesons destabilizes the strange quark matter. If the strength of the vector coupling is the same as in hadronic matter, strangelets can not be formed. For the case of β equilibrium, there is no strange quark matter which can be stable against hadron emission even without vector meson interactions.
