Abstract

The lepton flavor violating decay τS-S → μ^-η was investigated using data sample of 84.3 fb^-1 accumulated with the Belle detector at KEK. The detection of η meson was observed through the decay modes of η→γγ and π⁺π ^-π⁰. The minimum photon energy requirement was reduced from 0.1 to 0.005 GeV, as photons from this decay were found to have softer energy distribution compared to those in η→γγ. The results show that an upper limit for branching fraction B < 3.4×10^-7 at about 90% confidence level.
