Abstract

We present a search for lepton-flavor-violating τ decays into three leptons (electrons or muons) using 782 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 between 1.5 × 10^{- 8} and 2.7 × 10^{- 8}.
