摘要： 最近在奇异介子物理领域的进展和未来展望被回顾。主要成果是NA48首次观察到稀有衰变KS->pi0ee和KS->pi0mumu，E949观察到新的K+->pinunu事件，以及KTeV、KLOE和NA48对K0->pienu衰变的新精密测量，这些努力旨在解决CKM矩阵中单位性的小偏差，涉及|Vus|耦合。 显示英文摘要

摘要： The most recent progress and future prospects in kaon physics are reviewed. Main results are the first observation of the rare decays KS->pi0ee and KS->pi0mumu by NA48, new K+->pinunu event observed by E949 and new precision measurements of K0->pienu decays by KTeV, KLOE and NA48 made in an effort to resolve the slight deviation from the unitarity in the CKM matrix, involving the |Vus| coupling.
