Phys. Rev. Lett. 62, 1236–1239 (1989)Refined measurement of the B-hadron lifetimeReceived 31 October 1988; published in the issue dated 13 March 1989 We report a new measurement of the average lifetime of hadrons containing bottom quarks. The B-hadron decays are tagged by identifying leptons at high transverse momentum. From a fit to the lepton impact-parameter distribution, the average B-hadron lifetime is found to be (0.98±0.12±0.13)×10-12 sec. © 1989 The American Physical Society URL:
