Abstract
This paper presents an update of the measurement of the mean lifetime of theB s 0 meson. CombiningD s−ℓ,D s−h,φ−ℓ and inclusive D s final states from the 3.2 million hadronic Z decays collected by DELPHI between 1991 and 1994, the B s 0 mean lifetime was measured to be:τ(B s 0 )=1.67±0.14 ps.
