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.

Available in PDF, EPUB and Kindle. Book excerpt: In this study, the decays B+c → J/[psi]D+s and B+c → J/[psi] D*+s are studied with the ATLAS detector at the LHC using a dataset corresponding to integrated luminosities of 4.9 and 20.6 fb-1 of pp collisions collected at centre-of-mass energies √s=7 TeV and 8 TeV, respectively. Signal candidates are identified through J/[psi] → [mu]+[mu]- and D(*)+s → [Phi][pi]+([gamma]/[pi]0) decays. With a two-dimensional likelihood fit involving the B+c reconstructed invariant mass and an angle between the [mu]+ and D+s candidate momenta in the muon pair rest frame, the yields of B+c → J/[psi]D+s and B+c → J/[psi] D*+s, and the transverse polarisation fraction in B+c → J/[psi] D*+s decay are measured.

Book excerpt: We present a study of the decays B{sup 0,+} --> J/???−?°K{sup 0,+}, using 467x106 B{anti B} pairs recorded with the BABAR detector. We present evidence for the decay mode X(3872) --> J/??, with product branching fractions B(B+ --> X(3872)K+) x B(X(3872) --> J/??) = [0.6 ± 0.2(stat) ± 0.1(syst)] x 10−5, and B(B° --> X(3872)K°) x B(X(3872) --> J/??) = [0.6 ± 0.3(stat) ± 0.1(syst)] x 10−5. A detailed study of the?+?−?° mass distribution from X(3872) decay favors a negative-parity assignment.
