Measurement of B-meson lifetimes using fully reconstructed B decays produced in pp collisions at s = 1.8 TeV

We present an improved measurement of b-meson lifetimes using fully reconstructed B-decays produced in pp collisions at s = 1.8 TeV, using 114 pb-1 of data collected at the Collider Detector at Fermilab. We obtain (B+) = 1.6360.058(stat)0.025(syst) ps, (B0) = 1.4970.073(stat)0.032(syst) ps and for the lifetime ratio (B+)/(B0) = 1.0930.066(stat)0.028(syst).
