This paper presents an update of the measurement of the mean lifetime of the B-s(0) meson. Combining D-s - l, D-s - h, phi - 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: tau(B-s(0)) = 1.67 +/- 0.14 ps.

Abstract
This paper presents an update of the measurement of the mean lifetime of the B-s(0) meson. Combining D-s - l, D-s - h, phi - 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: tau(B-s(0)) = 1.67 +/- 0.14 ps.
