Abstract

We describe measurements of inclusive branching ratios of the tau lepton to KS 0 and charged K* (892) using Z0→τ+τ- candidates collected with the OPAL detector at LEP during 1990-1992. From a total of 61 854 tau candidates we find: Br(τ-→KS 0X-ντ) = 0.97 ± 0.09(stat.) ± 0.06(syst.) %Br(τ-→K*-≥0h0ντ) = 1.94 ± 0.27(stat.) ± 0.15(syst.) % where X- refers to any configuration of particles with charge -1 and h0 is any neutral hadron other than the KS 0. © 1994.
