Abstract
We have searched for neutrinoless τ lepton decays into ℓhh or ℓ V0, where ℓ stands for an electron or muon, h for a charged light hadron, π or K, and V0 for a neutral vector meson, ρ0, K* (892)0 and φ{symbol}, using a 158 fb-1 data sample collected with the Belle detector at the KEKB e+ e- collider. Since the number of events observed are consistent with the expected background, we set upper limits on the branching fractions in the range of (1.6 - 8.0) × 10-7 for various decay modes at the 90% confidence level.
