Abstract

Recent results and the current situation on the search for lepton-flavor-violating τ decays are presented. B-factories have successfully accumulated data samples of >109τ pairs, and recently performed searches for τ→3ℓ, ℓV0 and ℓf0(980). The upper limit of the branching ratio was obtained to be ∼O(10−8). The results have ruled out some parts of the parameter space for the models beyond the Standard Model, such as the SUSY+seesaw mechanism.
