Abstract

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