标题： Hyperon-rich Matter and Kaons in Matter

摘要： 我们讨论了在高密度物质内部中子星的状态方程，考虑了超子以及相对论平均场模型中可能出现的K介子凝聚。 我们发现超子在高密度物质中是有利的，并且它们的出现使得K介子凝聚相的存在相当不可能。 还给出了关于亚阈值能量重离子碰撞中K介子近期测量结果的影响。 显示英文摘要

摘要： We discuss the equation of state of neutron stars in the dense interior considering hyperons and the possible onset of kaon condensation within the relativistic mean field model. We find that hyperons are favoured in dense matter and that their appearance make the existence of a kaon condensed phase quite unlikely. Implications for the recent measurements of kaons in heavy ion collisions at subthreshold energy are also given.
