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.
