摘要：
We present recent studies of T lepton decays into final states containing kaons at BABAR. The preliminary measurement of the branching fraction B(tau(-) -> (K) over bar (0)pi(-)pi(0)nu(tau)) is reported. We also present the preliminary determination of the mass and width of the K* (892)(-) resonance using the invariant K-s(0)pi(0) mass spectrum in the decay tau(-) -> (K) over bar (0)pi(-)nu(tau) . Further, a recent analysis of the decays tau(-) -> K-nu(tau) and tau(-) -> nu(tau) is reported, which includes a determination of the CKM-matrix element vertical bar V-us vertical bar.
