Abstract

The inclusive branching ratio for the process b --> tau (-)(v) over bar X-tau has been measured using hadronic Z decays collected by the OPAL experiment at LEP in the years 1992-2000. The result is: BR(b --> tau (-)(v) over bar X-tau) = (2.78 +/- 0.18 +/- 0.51)%. This measurement is consistent with the Standard Model expectation and puts a constraint of tan beta /M-H(+/-) <0.53 GeV-1 at the 95% confidence level on Type II Two Higgs Doublet Models.
