Improved limits on lepton-flavor-violating τ decays to ℓ, ρ, K*, and K̄*

Abstract:

We search for the neutrinoless, lepton-flavor-violating tau decays τ-→-V0, where is an electron or muon and V0 is a vector meson reconstructed as →K+K-, ρ→π+π-, K*→K+π-, K̄*→K-π+. The analysis has been performed using 451fb-1 of data collected at an e+e- center-of-mass energy near 10.58 GeV with the BABAR detector at the PEP-II storage rings. The number of events found in the data is compatible with the background expectation, and upper limits on the branching fractions are set in the range (...
