Abstract

We present measurements of the linear polarization amplitudes and the strong relative phases that describe the flavor-untagged decays Bd0J/ψK*0 and Bs0J/ψϕ in the transversity basis. We also measure the mean lifetime τ¯s of the Bs0 mass eigenstates and the lifetime ratio τ¯s/τd. The analyses are based on approximately 2.8fb1 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 Bd0J/ψK*0 decay.
