MEASUREMENT OF THE INCLUSIVE B-]TAU-NU-X BRANCHING RATIO
Using the L3 detector, the branching ratio BR(b → πνX) has been measured using a sample of Z → bb events tagged by high momentum and high transverse momentum leptons in one hemisphere and with missing energy in the opposite hemisphere. From a sample of 948 000 hadronic events we find BR(b → πνX) = (...
