We present measurements of the linear polarization amplitudes and the strong relative phases that describe the flavor-untagged decays Bd0JK+0 and Bs0J/ψφ in the transversity basis. We also measure the mean lifetime τs of the Bd0 mass eigenstates and the lifetime ratio τsd. 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 i>Bd0JK+0 decay.
