Abstract

The lifetime of the Lambda(b)(0) baryon has been measured using 3.6 million hadronic Z(0) decays recorded by the OPAL detector at LEP from 1990 to 1994. A sample of Lambda(b)(0) decays is obtained using partially reconstructed semileptonic decays involving Lambda(c)(+)l(-) combinations, where the Lambda(c)(+) is reconstructed from its decay to a pK(-) pi(+) final state. From the 69 +/- 13 Lambda(c)(+)l(-) combinations attributed to Lambda(b)(0) decays in this data sample, we measure tau(Lambda(b)(0)) = 1.14(-0.19)(+0.22) +/- 0.07 ps, where the errors are statistical and systematic, respectively.
