Search for Lepton Flavor Violating τ Decay at Belle

We review recent searches for lepton flavor violation in τ− decays based on >500 fb−1 of data collected with the Belle detector at the KEKB asymmetric-energy e+e− collider. No evidence for these decays is observed and we set 90% confidence level upper limits on the branching fractions at the O(10−8) level.
