Abstract

We have searched for neutrinoless τ lepton decays into three charged leptons using an 87.1fb^-1 data sample collected with the Belle detector at the KEKB e⁺e^- collider. Since the number of signal candidate events is compatible with that expected from the background, we set 90% confidence level upper limits on the branching fractions in the range (1.9-3.5)×10^-7 for various decay modes τ ^-→ℓ^-ℓ⁺ℓ^- where ℓ represents e or μ.
