Charged kaon production in tau lepton decays
The result of an experiment performed at the PEP e/sup +/e/sup -/ storage ring which operated at 29.0 GeV/c/sup 2/ is presented. The DELCO detector, which emphasizes Cherenkov particle identification, is used to measure the production of charged kaons in tau decays. The branching ratio the three Cabibbo-suppressed decays are measured, and the branching ratio of the Cabibbo-favored decay is measured. These branching ratio measurements provide a test e-..mu..-tau universality and are in agreement with and the predictions of SU(3) sum rules. The invariant mass distribution of the K/sup +/K/sup -/..pi.. system in the exclusive tau/sup +/-/ ..-->.. K/sup +/K/sup -/..pi../sup +/-/nu/sub tau/ channel is used to set a limit of 157 MeV/c/sup 2/ at 95% CL on the tau neutrino mass.
