Abstract

From a sample of about 75000 tau decays measured in the ALEPH detector, 1-prong charged kaon decays are identified by the dE/dx measurement in the central detector. The resulting branching ratios for the inclusive and exclusive modes are: B(tau --> nu(tau)K- greater-than-or-equal-to 0pi0 greater-than-or-equal-to 0K0) = (1.60 +/- 0.07 +/- 0.12)%, B(tau --> nu(tau)K-) = (0.64 +/- 0.05 +/- 0.05)%, B(tau --> nu(tau)K-pi0) = (0.53 +/- 0.05 +/- 0.07)% and B(tau --> nu(tau)K-pi0pi0) = (0.04 +/- 0.03 +/- 0.02)%. Exclusive modes are corrected for measured K(L)0 production. The rate for tau --> nu(tau)K- agrees well with the prediction based on tau - mu universality.
