Description

We report on recent searches for lepton flavour violating decays of the τ lepton: τ- → (ell)- KS0, τ- → (ell)-(ρ0, K*0, (bar K)*0, φ). These preliminary results use data samples collected by the BaBar detector at the SLAC PEP-II B factory corresponding to integrated luminosities of 469 fb-1 for the τ- → (ell)-KS0 and 451 fb-1 for the τ- → (ell)-(ρ0, K*0, (bar K)*0, φ) searches. No statistically significant signal has been observed in any of these channels and we set upper limits on their branching fractions between 0.8-18.2 x 10-8 at 90% confidence level.
