- From a fit to the impact parameter distribution of lepton tracks from semileptonic b decay, the lifetime of B-hadrons produced in e+e- collisions at the Z0 is measured to be 1.32±0.08 (stat.)±0.09(syst.) ps. Combined with an earlier measurement of the branching ratio Br(B→ℓνX), the CKM matrix element |Vcb| is determined to be 0.046±0.002 (exp.)-0.003+0.004 (theory). © 1991.
