| Résumé : | The study of the properties of inclusive production of Ds mesons and of events in which a φ{symbol} and a muon are present in the same jet provides two independent measurements of the probability, fsw, for a heavy quark to hadronize into a strange B or D meson. The data sample analysed corresponds to 243,000 hadronic Z0 decays. The combined value of these measurements is fsw=0.19±0.06±0.08. From the flight distance distributions of Ds and of (φ{symbol}-lepton) secondary vertices, with the lepton emitted at high transverse momentum relative to the jet axis, two values are obtained for the Bs0 meson lifetime. Combining these measurements with a previous result based on the study of Ds-μ events, the Bs0 meson lifetime is measured to be: 0.96±0.37 ps. © 1994 Springer-Verlag. |
