Book Description
The average b-hadron lifetime has been measured using a high statistics sample of[ital B][r-arrow][ital J]/[psi][Chi] decays recorded with the Collider Detector at Fermilab. We use a sample with an integrated luminosity of[approx] 90[ital pb][sup -1] recorded during the 1994-95 running period. The decay vertices of[approx] 62656 inclusive[ital J]/[psi][r-arrow][mu][sup+][mu][sup -] candidates have been reconstructed using information from a silicon vertex-detector. The measured[ital B]lifetime, which is the average over all b-hadrons produced in[ital p][ital[anti p]] collisions at[radical]s= 1.8 TeV weighted by their branching ratios into[ital J]/[psi], is 1.524[+-] 0.015 ([ital stat])[sup+0.035][sub -0.026] ([ital sys]) ps. The precision of this measurement is significantly improved compared to the inclusive lifetime measurement published previously using[approx] 10[ital pb][sup -1].

Book Description
The average B hadron lifetime was measured using data collected with the SLD detector at the SLC in 1993. From a sample of -50,000 Z° events, a sample enriched in Z° → b{bar b} was selected by applying an impact parameter tag. The lifetime was extracted from the decay length distribution of inclusive vertices reconstructed in three dimensions. A binned maximum likelihood method yielded an average B hadron lifetime of?{sub B} = 1.577±0.032(stat.)±0.046(syst.) ps.

Book Description
The authors present preliminary measurements of the average B hadron lifetime using a sample of 50,000 Z[sup 0] events collected by SLD at the SLC in 1993. Their first technique uses the impact parameter of tracks in jets opposite tagged b jets. They obtain [tau][sub B]([delta]) = 1.617 [+-] 0.048 [+-] 0.086 ps, and [tau][sub B]([Sigma][delta]) = 1.627 [+-] 0.054 [+-] 0.132 ps from single and summed impact parameter distributions. The second technique uses inclusive vertices reconstructed in three dimensions. From the decay length distribution, they extract [tau][sub B] = 1.577 [+-] 0.032 [+-] 0.046 ps.
