| Description: |
We report on analyses of tau lepton decays τ -→ηK-ντ and τ-→ηπ-ντ, with η→π+π-π0, using 470fb-1 of data from the BABAR experiment at PEP-II, collected at center-of-mass energies at and near the Υ(4S) resonance. We measure the branching fraction for the τ-→ηK-ντ decay mode, B(τ-→ηK-ντ)=(1.42±0. 11(stat)±0.07(syst))×10-4, and report a 95% confidence level upper limit for the second-class current process τ -→ηπ-ντ, B(τ-→ηπ-ντ) |
