Abstract

We present a measurement of the Bs0 lifetime in fully √and partially reconstructed Bs0 → Ds−(φπ−)X decays in 1.3 fb−1 collected in pp collisions at s = 1.96 TeV by the CDF II de- tector at the Fermilab Tevatron. We measure τ(Bs0) = 1.518 ± 0.041 (stat.) ± 0.027 (syst.) ps. The ratio of this result and the world average B0 lifetime yields τ(Bs0)/τ(B0) = 0.99 ± 0.03, which is in agreement with recent theoretical predictions.
