标题： Rare K Decays: Present and perspectives with NA62

摘要： 稀有K介子衰变提供了独特的机会来检验标准模型并探测其可能的扩展。 通过测量比值 R_K = G(K+- 到 e+- ν)/G(K+- 到 mu+- ν) 的轻子普适性测试的最终结果也已呈现，同时介绍了对稀有衰变 K+- 到 pi+- γ γ 和 K+ 到 e+ ν γ 的研究现状。 NA62实验的主要目标是在两年的数据采集中以10%的精度测量 Br(K+ 到 pi+ ν 反ν) 衰变。 描述了探测器配置以及分析技术。 显示英文摘要

摘要： Rare kaon decays provide unique opportunity to test the Standard Model and probe its possible extensions. The final result on the lepton universality test by measuring the ratio R_K = G(K+- to e+- nu)/G(K+- to mu+- nu) is presented as well as the status of the study of the rare decays K+- to pi+- gamma gamma and K+ to e+ nu gamma. The primary goal of the NA62 experiment is the measurement of the Br(K+ to pi+ nu anti-nu) decay with a precision of 10% in two years of data taking. The detector setup together with the analysis technique is described.
