Title: Measurement of the Bs 0 Lifetime in Fully and Partially Reconstructed Bs 0 -> Ds - (phi pi -)X Decays in pp¯ Collisions at √s = 1.96 TeV

The authors present a measurement of the B s 0 lifetime in fully and partially reconstructed B s 0 = D s 0(φπ -)X decays in 1.3 fb -1 collected in pp¯ collisions at √s = 1.96 Tev by the CDF II detector at the Fermilab Tevatron. They measure τ(B s 0) = 1.518 ± 0.041 (stat.) ± 0.027 (syst.) ps. The ratio of this result and the world average B 0 lifetime yields τ(B s 0)/τ(B 0) = 0.99 ± 0.03, which is in agreement with recent theoretical predictions.
