Measurement of the inclusive b →τνX branching ratio

Document type: Articulo

Abstract

Using the L3 detector, the branching ratio BR(b → πνX) has been measured using a sample of Z → b 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) = (2.4 ± 0.7 (stat.) ± 0.8 (syst.))%.
