Search for the rare decays K0L-->μe and K0L-->ee
Abstract
A search for the rare decays K0L-->μe and K0L-->ee was performed at the KEK 12-GeV Proton Synchrotron. No event was observed in the fiducial region for the decay K0L-->μe. There was one event in the fiducial region for the decay K0L-->ee, which was indistinguishable from the background. The upper limits on the branching ratios at 90% confidence level were B(K0L-->μe)<9.4×10-11 and B(K0L-->ee)<1.6×10-10.
