Abstract

Precision study of CP violation is one of the major themes in high energy physics for the next decade(s). The rare K decays K+ --> pi+ nu nubar and KL --> pi0 nu nubar are interesting since fundamental parameters of the Standard Model can be extracted from the branching ratios with very little theoretical uncertainty. Comparison of these fundamental parameters with those extracted from precision studies of B mesons will provide a crucial test of our understanding of CP violation, and will hopefully give some hint of physics beyond the Standard Model. In this talk I will cover the current status of two experiments at BNL (E949 and KOPIO) which have been designed to exploit these two rare K decays.
