Abstract
We here report on a search for lepton-flavor violating Ï decays, Ïâ(μ/e)+(Ï0/η/ηâ²), with a 153.8 fbâ1 data recorded by the Belle detector at the KEKB e+eâ asymmetric-energy collider. For each of the six decay modes, the observed yield is compatible with background and the 90% confidence level upper limits on the branching fraction are obtained as 0.13 â1.0 à 10-6 which are a factor of 9 to 74 times better than previous measurements.
