Résumé

We present a study of the decay τ^- → K_S π^- ν_τ using a 351 fb^-1 data sample collected with the Belle detector. The analysis is based on 53, 110 lepton-tagged signal events. The measured branching fraction B (τ^- → K_S π^- ν_τ) = (0.404 ± 0.002 (stat .) ± 0.013 (syst .)) % is consistent with the world average value and has better accuracy. An analysis of the K_S π^- invariant mass spectrum reveals contributions from the K^* (892)^- as well as other states. For the first time the K^* (892)^- mass and width have been measured in τ decay: M (K^* (892)^-) = (895.47 ± 0.20 (stat .) ± 0.44 (syst .) ± 0.59 (mod .)) MeV / c², Γ (K^* (892)^-) = (46.2 ± 0.6 (stat .) ± 1.0 (syst .) ± 0.7 (mod .)) MeV. The K^* (892)^- mass is significantly different from the current world average value.
