Abstract: (Elsevier)

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 , ω , K∗0 , 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 , ℓK∗0 , ℓK¯∗0 and ℓρ0 modes.
