The lifetime of the Bs0 meson is measured using the exclusive decay mode Bs0 → J / ψ φ, where J/ψ → μ+μ- and φ → K+K-. The data sample consists of 110 pb-1 of p p̄ collisions at √s = 1.8 TeV, collected by the CDF detector at the Fermilab Tevatron collider during 1992-1995. We find 58 ± 12 signal events, and the Bs0 meson lifetime is determined to be τBs0; = 1.34-0.19+0.23(stat) ± 0.05(syst) ps. This result is consistent with previous measurements of the Bs0, B+, and Bd0 meson lifetimes and with theoretical predictions.
