Abstract: (APS)
We use a data sample of 2.8 × 106 produced τ-pair events, obtained with the CLEO II detector, to measure B(τ−→h−h+h−(π0)ντ), where h refers to either a charged π or K. These branching fractions are measured with samples of lepton-tagged and 3 vs 3 events. We find B(τ−→h−h+h−ντ)=0.0951±0.0007±0.0020 and B(τ−→h−h+h−π0ντ)=0.0423±0.0006±0.0022. We also measure B(τ−→ωh−ντ)=0.0195±0.0007±0.0011.- electron positron: colliding beams
