Abstract

We have measured the branching ratios for several decay modes. We use e+e-+- events accumulated with the TPC/Two-Gamma facility at the SLAC e+e- storage ring PEP. The data correspond to an integrated luminosity of 77 pb-1 at a center-of-mass energy of 29 GeV. The one- and three-charged-particle inclusive branching ratios of the decay are measured to be B1=(84.7±1.0)% and B3=(15.1±1.0)%, where B1+B3 is constrained to be 99.85%. The branching ratios of the two leptonic decay modes are B(-e- 1/2»e1/2)=(18.4±1. 6)% and B(-'1/4- 1/2»1/41/2)=(17.7±1.4)%. If we then assume lepton universality, we obtain B(-e- 1/2e1/2)=(18.3±0.9)% and B(-'1/4- 1/2»1/41/2)=(17.8±0.9)%. We measure the Cabibbo-allowed semihadronic decay mode B(--+neutral particles)=(47.0±1.5)%, and the Cabibbo-suppressed decay mode B(-K-+neutral particles)=(1.6±0.4)%. By looking for associated photons, we find B(-K-0+neutral particles) to be (1.2±0.6)%. Using the channel K*-KSO+-, we find B(-K*-(892)+neutral particles)=(1.4±0.9)%. The quoted errors are the combined statistical and systematic errors.
