KTEV results on chiral perturbation theory

Research output: Contribution to conferencePaperpeer-review

Abstract

The KTeV experiment has carried out a broad program of studies of rare kaon decays. In this paper we present results on KL → π0γγ, KL → π0e+eγ and KL → π0π0γ. These decays provide a window for testing chiral perturbation theory at O(p6). We find BR(KL → π0γγ) = (1.30 ± 0.03) × 10−6, BR(KL → π0e+eγ) = (1.90±0.16±0.12)×10−8, and set the limit BR(KL → π0π0γ) < 2.32×10−7. The KTeV measurements are competitive with or better than the world’s best results in these decays.
