New search for τ→μγτ→μγ and τ→eγτ→eγ decays at Belle

We report on a search for the lepton flavor violating τ−→μ−γτ−→μ−γ and τ−→e−γτ−→e−γ 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−→μ−γ)<4.5×10−8B(τ−→μ−γ)<4.5×10−8 and B(τ−→e−γ)<1.2×10−7B(τ−→e−γ)<1.2×10−7.
