Abstract

The average b-hadron lifetime has been measured using a high statistics sample of B --> J/psi) X decays recorded with the Collider Detector at Fermilab. The decay vertices of 5344 inclusive J/psi --> mu+mu-candidates have been reconstructed using information from a silicon vertex detector. The measured B lifetime, which is the average over all b hadrons produced in ppBAR collisions at square-root s = 1.8 TeV weighted by their branching ratios into J/psi, is 1.46 +/- 0.06(stat) +/- 0.06(syst) ps.
