posted on 2023-06-08, 15:31 authored by T Aaltonen, Alessandro CerriAlessandro Cerri, The CDF CollaborationWe present a measurement of the Bs0 lifetime in fully vand partially reconstructed Bs0 ? Ds-(fp-)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 t(Bs0) = 1.518 ± 0.041 (stat.) ± 0.027 (syst.) ps. The ratio of this result and the world average B0 lifetime yields t(Bs0)/t(B0) = 0.99 ± 0.03, which is in agreement with recent theoretical predictions.
