Measurement of b Hadron Lifetimes in Exclusive Decays Containing a J/psi in pp[over-bar] Collisions at [sqrt]s=1.96 TeV
We report on a measurement of b-hadron lifetimes in the fully reconstructed decay modes B+-->J/psiK+, B0-->J/psiK*(892)0, B0-->J/psiKs0, and Lambdab0-->J/psiLambda0 using data corresponding to an integrated luminosity of 4.3 fb-1, collected by the CDF II detector at the Fermilab Tevatro...

| description | We report on a measurement of b-hadron lifetimes in the fully reconstructed decay modes B+-->J/psiK+, B0-->J/psiK*(892)0, B0-->J/psiKs0, and Lambdab0-->J/psiLambda0 using data corresponding to an integrated luminosity of 4.3 fb-1, collected by the CDF II detector at the Fermilab Tevatron. The measured lifetimes are tau(B+)=[1.639±0.009(stat)±0.009(syst)] ps, tau(B0)=[1.507±0.010(stat)±0.008(syst)] ps, and tau(Lambdab0)=[1.537±0.045(stat)±0.014(syst)] ps. The lifetime ratios are tau(B+)/tau(B0)=[1.088±0.009(stat)±0.004(syst)] and tau(Lambdab0)/tau(B0)=[1.020±0.030(stat)±0.008(syst)]. These are the most precise determinations of these quantities from a single experiment. |
