标题： Chiral perturbation in dense matter and meson condensation controversy

摘要： 一个在可能的K介子凝聚研究中的突出问题是手征微扰理论的结果与PCAC加电流代数方法的结果之间存在的显著差异。我在这里讨论造成这种差异的原因以及为解决这个问题需要做些什么。此外，我指出检查现有K介子凝聚处理中普遍采用的非相对论近似的有效性的重要性。 显示英文摘要

摘要： An outstanding problem in the study of possible kaon condensation is the striking discrepancy between the results of chiral perturbation theory and those of the PCAC-plus-current-algebra approach. I discuss here what causes this discrepancy and what needs to be done to solve the problem. In addition, I point out the importance of examining the validity of the non-relativistic approximation universally employed in the existing treatments of kaon condensation.
