摘要: 把 FST模型推广到包含奇异性的情形,并在平均场近似下用它来研究含有核子、Λ超子和Ξ超子的奇异强子物质的性质.讨论了有效重子质量对介质密度和奇异数含量的依赖性以及奇异强子物质的饱和性和稳定性. The strange hadronic matter with nucleon, Λ hyperon and Ξ hyperonis was studied by using an effective model in a mean field approximation. The density dependence of the effective baryon masses as well as the saturation properties and stabilities of the strange hadronic matter were discussed. The result indicates a quite large strangeness fraction range where the multi hyperon nuclear matter is stable against particle emission. In the large strangeness fraction region the Ξ component dominates...
