Measurement of inclusive B semileptonic branching fractions at the Z resonance
This document presents a new measurement of inclusive b semileptonic branching fractions [special characters omitted] and [special characters omitted]. The [special characters omitted] and [special characters omitted] are separated by a means that uses correlation between the final state lepton charge and that of its parent b quark as a constraint. Monte Carlo counts of electrons and muons are calibrated to the data using a newly developed technique based on pairs of mutually independent tests for each particle hypothesis separately. The data sample consists of about 550,000 hadronic Z decays collected at the SLD between 1993 and 1998. Upon analysis of electron and muon counts in 61602 hadronic event hemispheres tagged as containing either a b or a b¯, we report [special characters omitted][special characters omitted]
