Available in PDF, EPUB and Kindle. Book excerpt: We present measurements of the linear polarization amplitudes and the strong relative phases that describe the flavor-untagged decays B{sub d} → J/[Psi] K* and B{sub s} → 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−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} → J/[Psi] K* decay.
