Measurement of the Bs0 lifetime in fully and partially reconstructed Bs0?Ds-(Fp ^-)X decays in p¯p collisions at vs=1.96TeV

Abstract: We present a measurement of the B0s lifetime in fully and partially reconstructed B0s?D?s(???)X decays in 1.3??fb?1 collected in p¯p collisions at ?s=1.96??TeV by the CDF II detector at the Fermilab Tevatron. We measure ?(B0s)=1.518±0.041(stat)±0.027(syst)??ps. The ratio of this result and the world average B0 lifetime yields ?(B0s)/?(B0)=0.99±0.03, which is in agreement with recent theoretical predictions.
