MEASUREMENT OF THE AVERAGE LIFETIME OF B-HADRONS
The average lifetime of b hadrons has been measured using the L3 detector at LEP, running at √s ≈ MZ. A b-enriched sample was obtained from 432538 hadronic Z events collected in 1990 and 1991 by tagging electrons and muons from semileptonic b hadron decays. From maximum likelihood fits to the electr...
