Abstract

The lifetime of the B0smeson using the exclusive decay mode B0s→J/ψφ where J/ψ→μ+μ and φ→K+K The data sample consists of 110 pb−1 of pp 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 B0s meson lifetime is determined to be TB0s=1.34+0.23−0.19(stat)±0.05(syst)ps. This result is consistent with previous measurements of theB0s, B+and B0dmeson lifetimes and with theoretical predictions.
