Abstract

A sample of 2610 electron candidates and 2762 muon candidates identified in hadronic Z⁰ decays has been used to measure the average b hadron lifetime. These data were recorded with the OPAL detector during 1990 and 1991. Maximum likelihood fits to the distributions of the lepton impact parameters yield an average b hadron lifetime of {Mathematical expression}, where the first error is statistical and the second systematic. This result is a weighted average over the semileptonic branching fractions and production rates of the b hadrons produced in Z⁰ decays.

N2 - A sample of 2610 electron candidates and 2762 muon candidates identified in hadronic Z0 decays has been used to measure the average b hadron lifetime. These data were recorded with the OPAL detector during 1990 and 1991. Maximum likelihood fits to the distributions of the lepton impact parameters yield an average b hadron lifetime of {Mathematical expression}, where the first error is statistical and the second systematic. This result is a weighted average over the semileptonic branching fractions and production rates of the b hadrons produced in Z0 decays.
