Abstract
The lifetimes of B+ and B-0 mesons are measured using a sample of 1500 00 hadronic Z(0) decays collected by the SLD experiment at the SLAG Li near Collider between 1993 and 1995. Two analyses are presented in whi ch the decay length and charge of the B meson are reconstructed. The f irst method uses a novel topological vertexing technique while the sec ond uses semi-inclusively reconstructed semileptonic decays. The topol ogical analysis yields a sample of 6033 (3665) charged (neutral) verti ces with good charge purity, whereas the semileptonic analysis yields a smaller sample of 634 (584) charged (neutral) decays with excellent charge purity. Combining the results from both analyses, we find tau(B +) = 1.66 +/- 0.06(stat) +/- 0.05(syst) ps, tau(B0) = 1.64 +/- 0.08(st at) +/- 0.08(syst) ps, and tau(B+)/tau(B0) = 1.01 +/- 0.07(stat) +/- 0 .06(syst).
