Abstract
Kaon production in one prong tau decays has been studied using data co llected with the DELPHI detector at the LEP collider. Charged kaons we re identified over a large momentum range by the DELPHI barrel Ring Im aging Cherenkov detector. The following branching ratios have been det ermined: BR(tau --> Knu(T)) = (0.85 +/- 0.18) %, BR(tau --> Knu(tau) g reater-than-or-equal-to 0 neutrals) = (1.54 +/- 0.24) %, BR(tau --> Kn u(tau) greater-than-or-equal-to 1 neutrals) = (0.69 +/- 0.25) %. The r esult for the exclusive branching ratio is consistent with the Standar d Model prediction based on tau - mu - e universality. In addition, ta u decay into K- was studied in the channel K*- --> K- pi0. The result BR(tau --> K-nu(tau)) x BR(K*- --> K- pi0) = (0.57 +/- 0.23)% was ob tained.
