Measurement of the average lifetime of b-hadrons in Z decays

Abstract:: We present a measurement of the average b-hadron lifetime τb at the e+e collider LEP. Using hadronic Z decays collected in the period from 1991 to 1994, two independent analyses have been performed. In the first one, the b-decay position is reconstructed as a secondary vertex of hadronic b-decay particles. The second analysis is an updated measurement of Tb using the impact parameter of leptons with high momentum and high transverse momentum. The combined result is τb = [1549 ± 9 (stat) ± 15 ...
