Title: Observation of the Decay K{sup +} yields P{sup +} v...

Abstract

We have observed 1 event consistent with the signature expected of the rare decay of a positive kaon to a positive pion and a neutrino anti-neutrino pair. In the examined momentum region of 211 to 230 MeV/c in the center of mass of the kaon we estimated the backgrounds to be about 0.08 ± 0.03 events. From this observation we estimate the branching ratio to be 4.2+9.7-3.5 x 10-10. In this presentation I will explain the experiment, and the analysis techniques. I will also discuss the expected improvements in the near future from the analysis of new data sets.
