Measurement of the Angular and Lifetime Parameters of the Decays B-d(0) -} J/psi K*(0) and B-s(0) -} J/psi phi (Art. No. 032001)

Abstract
We present measurements of the linear polarization amplitudes and the strong relative phases that describe the flavor-untagged decays B-d(0) --} J/psi K*(0) and B-s(0) --} J/psi phi in the transversity basis. We also measure the mean lifetime (tau) over bar (s) of the B-s(0) mass eigenstates and the lifetime ratio (tau) over bar (s)/tau(d).
The analyses are based on approximately 2.8 fb(-1) of data recorded with the D0 detector. From our measurements of the angular parameters we conclude that there is no evidence for a deviation from flavor SU( 3) symmetry for these decays and that the factorization assumption is not valid for the B-d(0) --} J/psi K*(0) decay.
