Measurement of the B0s lifetime in the exclusive decay channel B0s ? J/ ??
Original language description
Using the exclusive decay B0s ?J/?(?+?-)? (K+K-), we report the most precise single measurement of the B0s lifetime . The data simple corresponds to an integrated luminosity pf approximatly 220 pb(-1) collected with D0 detector at the Fermilab Tevatron Collider on 2002-2004. We reconstruct 337 signal candidates, from which we extract the B0s lifetime . We also report a measurement for the lifetime of the B0 meson using the exclusive decay B0 ?J/?(?+?-)K*0(K+K-)(892)(K+?-).
