Description
The lifetime of the Bs meson is measured using the semileptonic decay Bs→Ds-l+νX. The data sample consists of 19.3 pb-1 of p bar p collisions at √s=1.8 TeV collected by the Collider Detector at Fermilab during 1992--1993. There are 76±8 l+Ds- signal events where the Ds is identified via the decay Ds-→φπ-, φ→K+K-. Using these events, the Bs meson lifetime is determined to be τs=1.42-0.23+0.27(stat)±0.11(syst) ps. A measurement of the Bs lifetime in a low statistics sample of exclusive Bs→J/ψφ decays is also presented in this paper
