Measurement of B hadron lifetimes using J/psi final states at CDF

Abstract:

The average bottom-hadron and individual B+, B0, and Bs0 meson lifetimes have been determined using decays with a J/ψ→μ+μ- in the final state. The data sample consists of 110 pb-1 of p̄p collisions at √s =1.8 TeV collected by the CDF detector at the Fermilab Tevatron collider during 1992-1995. For the average lifetime of B hadrons decaying into J/ψ+X, we obtain <τb>=1.533±0.015(stat)-0.031+0.035(syst) ps. For the B+ and B0 meson lifetimes, we determine τ(B+)=1.68±0.07(stat) ±0.02(syst) ...
