Abstract

We search for lepton-flavor and lepton-number-violating. Τ decays into a lepton (ℓ= electron or muon) and two charged mesons (h,h'=π± or K±) using 854 fb^-1 of data collected with the Belle detector at the KEKB asymmetric-energy e⁺e^- collider. We obtain 90% confidence level upper limits on the. Τ→ℓhh' branching fractions in the range. (2.0-8.4)×10^-8. These results improve upon our previously published upper limits by factors of about 1.8 on average.
