论文摘要
由于在标准模型中强烈抑制改变了风味的中性电流过渡，因此稀有的kaon衰变构成了限制假设的新物理相互作用的精湛工具。同时，它们提供了许多对标准模型本身的有趣测试，对短距离电动级尺度和长距离QCD动力学都很敏感。介绍了当前状态的简要概述。还讨论了直接CP侵略比的标准模型预测$ \ VAREPSILON'/\ VAREPSILON $。
Owing to the strong suppression of flavour-changing neutral-current transitions in the Standard Model, rare kaon decays constitute a superb tool to constrain hypothetical new-physics interactions. At the same time, they provide many interesting tests of the Standard Model itself, being sensitive both to short-distance electroweak scales and to the long-distance QCD dynamics. A brief overview of the current status is presented. The Standard Model prediction for the direct CP-violating ratio $\varepsilon'/\varepsilon$ is also discussed.
