Abstract

We have searched for neutrinoless τ lepton decays into ℓ and V⁰, where ℓ stands for an electron or muon, and V⁰ for a vector meson (φ{symbol}, ω, K^{* 0}, over(K, ̄)^{* 0} or ρ⁰), using 543 fb^-1 of data collected with the Belle detector at the KEKB asymmetric-energy e⁺ e^- collider. No excess of signal events over the expected background has been observed, and we set upper limits on the branching fractions in the range (5.9 - 18) × 10^-8 at the 90% confidence level. These upper limits are significantly more restrictive than our previous results for the ℓφ{symbol}, ℓ K^{* 0}, ℓ over(K, ̄)^{* 0} and ℓ ρ⁰ modes.
