Precision Standard Model Tests with Kaons
Abstract
In kaon physics, several new precision measurements on flavour variables and CP violation have performed in the recent years. Presented are a new precise determination of the CKM parameter |Vus|, which combines the results of all experiments together with recent theoretical progress, and new measurements of the ratio RK = Gamma(K+ -> e+ nu)/Gamma(K+ -> mu+ nu), which is sensitive to contributions of a possible charged Higgs in the SUSY framework. Also, final results of a precision search for direct CP violation in charged kaon decays are presented.
