Measurement of the lifetime of the B-s(0) meson using the exclusive decay mode B-s(0)->J/psi phi
- Abstract:
- The lifetime of the Bs 0 meson is measured using the exclusive decay mode Bs 0 → 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 Bs 0 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 Bs 0, B+, and Bd 0 meson lifetimes and with theoretical predictions.
