New Search for tau -> mu gamma and tau -> e gamma Decays at Belle

Abstract

We report on a search for the lepton flavor violating tau- -> mu- gamma and tau- -> e- gamma decays based on 535/fb of data accumulated at the Belle experiment. No signal is found and we set 90% confidence level upper limits on the branching ratios Br(tau- -> mu- gamma) < 4.5x10^-8 and Br(tau- -> e- gamma) < 1.2x10^-7.

15 pages, 13 figures, the exponent of the upper limit for the tau -> e gamma in the abstract is corrected
