KTeV results on kaon radiative decays

Research output: Contribution to journalConference articlepeer-review


The KTeV experiment has carried out a broad program of studies of rare kaon decays. In this paper we present results on KL →π0 KL →π0e+e-?and KL →π eνe+e-. These decays provide a window for testing chiral perturbation theory. We find BR(KL →π0) = (1.30± 0.03)×10-6,BR(K L→π0e+e-) = (1.90±0.16±0.12)×10-8, and BR(K L→π±eνe +e-)=(1.29±0.01±0.04)×10 -5. The KTeV measurements are competitive with or better than the world's best results in these decays.
