Abstract
We present a measurement of the B-s(0) lifetime in fully and partially reconstructed B-s(0) -> D-s(-)(phi pi(-))X decays in 1.3 fb(-1) collected in p (p) over bar collisions at root s = 1.96 Tev by the CDF II detector at the Fermilab Tevatron. We measure tau(B-s(0)) = 1.518 +/- 0.041(stat) +/- 0.027(stat) ps. The ratio of this result and the world average B-0 lifetime tau(B-s(0))/tau(B-0) = 99 +/- 0.03, which is in agreement with recent theoretical predictions.
