Abstract

We present an improved measurement of b-meson lifetimes using fully reconstructed B-decays produced in p(p) over bar collisions at roots = 1.8 TeV, using 114 pb(-1) of data collected at the Collider Detector at Fermilab. We obtain tau(B+) = 1.636+/-0.058(stat)+/-0.025(syst) ps, tau(B-0) = 1.497+/-0.073(stat)+/-0.032(syst) ps and for the lifetime ratio tau(B+)/tau(B-0) = 1.093+/-0.066(stat)+/-0.028(syst).
