Measurements of the inclusive branching ratios of τ-leptons to K0S and charged K∗(892)

We describe measurements of inclusive branching ratios of the tau lepton to KS0 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−→KS0X−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 KS0.
