Measurement of the Lifetime Difference in the B_s^0 System
D0 Collaboration, V. M. Abazov
We present a study of the decay B_s^0 -> J/psi phi We obtain the CP-odd fraction in the final state at time zero, R_perp = 0.16 +/- 0.10 (stat) +/- 0.02 (syst), the average lifetim…

Measurement of Semileptonic Branching Fractions of B Mesons to Narrow D** States
D0 Collaboration, V. Abazov
Using the data accumulated in 2002-2004 with the DO detector in proton-antiproton collisions at the Fermilab Tevatron collider with centre-of-mass energy 1.96 TeV, the branching fr…
