New search for τ→μγ and τ→eγ decays at Belle
Abstract
We report on a search for the lepton flavor violating τ→μγ and τ→eγ decays based on 535 fb-1 of data accumulated at the Belle experiment. No signal is found and we set 90% confidence level upper limits on the branching ratios B(τ→μγ)<4.5×10 and B(τ→eγ)<1.2×10.
