Abstract
An upper limit on the lifetime difference of short- and long-lived B-s (0) masons has been obtained using an inclusive bottom hadron sample f rom 2 million hadronic Z decays collected by the L3 experiment at LEP. A lifetime fit has been performed on data samples separately enriched in neutral and charged b hadrons. An experimental upper limit on the decay rate difference of short- and long-lived B-s(0) masons of (\Delt a Gamma\/Gamma)(Bs0) < 0.67 (95% C.L.) has been determined. In additio n, the lifetimes of B + and B-d(0) mesons have been measured to be tau (B+) = 1.66 +/- 0.06 +/- 0.03 ps and tau(B-d(0)) = 1.52 +/- 0.06 +/- 0 .04 ps, where the first errors are statistical and the second are syst ematic.
