    AbstractFrom 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).
