Abstract

We present a measurement of the Bs0 lifetime in fully and partially reconstructed Bs0→Ds-(Φπ -)X decays in 1.3fb -1 collected in pp̄ collisions at √s=1.96TeV by the CDF II detector 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. © 2011 American Physical Society.
