R. Akers et al., MEASUREMENTS OF THE INCLUSIVE BRANCHING RATIOS OF TAU-LEPTONS TO K-S(0) AND CHARGED K-ASTERISK(892), Physics letters. Section B, 339(3), 1994, pp. 278-292
We describe measurements of inclusive branching ratios of the tau lept
on to K-S(0) and charged K(892) using Z(0)-->tau(+)tau(-) candidates
collected with the OPAL detector at LEP during 1990-1992. From a total
of 61 854 tau candidates we find: )(0)X(-)nu(tau))=0.97+/-0.09(stat.)
+/-0.06(syst.)% Br(tau(-)-->K(-)greater than or equal to 0h(0) nu(tau
))=1.94+/-0.27(stat.)+/-0.15(syst.)% where X(-) refers to any configur
ation of particles with charge -1 and h(0) is any neutral hadron other
than the K-S(0).
