| Résumé : | This paper presents an update of the measurement of the mean lifetime of the Bs0 meson. Combining Ds-ℓ, Ds-h, φ-ℓ and inclusive Ds final states from the 3.2 million hadronic Z decays collected by DELPHI between 1991 and 1994, the Bs0 mean lifetime was measured to be:τ(Bs0)=1.67±0.14 ps. © 1996 Springer-Verlag. |
