Measurements of BR (b -> tau- nubar_tau X) and BR (b -> tau- nubar_tau D*+- X) and Upper Limits on BR (B- -> tau- nubar_tau) and BR (b -> s nu nubar)

ALEPH Collaboration

Inclusive branching ratios involving b to tau transitions are measured in approximately four million hadronic Z decays collected by the ALEPH detector at LEP. The fully-inclusive b…
