# Study of Decays $B_d \to J/\psi+ K^*$ and $B_s \to J/\psi+ \phi$ with the D0 detector

### Description

We present measurements of the linear polarization amplitudes and the strong relative phases that describe the flavor-untagged decays B{sub d} {yields} J/{Psi} K* and B{sub s} {yields} J/{Psi}{phi} in the transversity basis. We also measure the mean lifetime of the B{sub s} mass eigenstates and the lifetime ratio. The analyses are based on approximately 2.8 fb{sup -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{sub d} ... continued below
