Abstract [en]

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.
