Abstract

The lifetime of the B⁰_smeson using the exclusive decay mode B⁰_s→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 B⁰_s meson lifetime is determined to be TB⁰_s=1.34^+0.23_{−0.19(stat)}±0.05(syst)ps. This result is consistent with previous measurements of theB⁰_s, B⁺and B⁰_dmeson lifetimes and with theoretical predictions.
