Abstract

The lifetime of the B-s(0) meson is measured using the exclusive decay mode B-s(0) --> J/psi phi, where J/psi --> mu(+)mu(-) and phi --> K+K-. The data sample consists of 110 pb(-1) of collisions at root 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 B-s(0) meson lifetime is determined to be tau(Bs0) = 1.34(-0.19)(+0.23)(stat) +/- 0.05(syst) ps. This result is consistent with previous measurements of the B-s(0), B+, and B-d(0) meson lifetimes and with theoretical predictions.
