Search for Lepton Flavor Violating Decays of the Neutral Kaon

Abstract

The Fermilab KTeV experiment has searched for lepton flavor violating decays of the KL meson in three decay modes. We observe no events in the signal region for any of the modes studied, and we set the following upper limits for their branching ratios at the 90% CL: BR(KL--> pi0 mu e) < 7.56 x 10^(-11); BR(KL--> pi0 pi0 mu e) < 1.64 x 10^(-10); BR(pi0 --> mu e) < 3.59 x 10^{-10).
