摘要 | The average lifetime of B hadrons has been measured by the ALEPH experiment at LEP. Events containing B hadrons are selected by the identification of leptons with high transverse momentum in hadronic Z decays, and the lifetime is extracted from a fit to the impact parameter distribution of the lepton tracks. From a sample of 1.7 x 10(5) hadronic Z decays a lifetime of 1.29 +/- 0.06 +/- 0.10 ps is measured. |
