Production rate and decay lifetime measurements ofB 0s mesons at LEP usingD s andϕ mesons

Abstract

The study of the properties of inclusive production ofD s mesons and of events in which a ϕ and a muon are present in the same jet provides two independent measurements of the probability,f ws , for a heavy quark to hadronize into a strangeB orD meson. The data sample analysed corresponds to 243,000 hadronicZ 0 decays. The combined value of these measurements isf ws =0.19±0.06±0.08. From the flight distance distributions ofD s and of (ϕ-lepton) secondary vertices, with the lepton emitted at high transverse momentum relative to the jet axis, two values are obtained for theB 0s meson lifetime. Combining these measurements with a previous result based on the study ofD s-μ events, theB 0s meson lifetime is measured to be: 0.96±0.37 ps.
