| 英文摘要 | Based upon flavor SU(3) symmetry, we perform global fits to charmless B decays into one pseudoscalar meson and one vector meson in the final state. We consider different symmetry breaking schemes and find that the one implied by naive scaling, where strangeness-conserving and strangeness-changing amplitudes are related by the ratio of appropriate decay constants, is slightly favored over the exact symmetry case. The ((rho) over bar, (eta) over bar) vertex of the unitarity triangle (UT) constrained by our fits is consistent with other methods within errors. We have found large color-suppressed, electroweak penguin and singlet penguin amplitudes when the spectator quark ends up in the final-state vector meson. Nontrivial relative strong phases are also required to explain the data. The best-fit parameters are used to compute branching ratio and CP asymmetry observables in all of the decay modes, particularly those in the B(s) decays to be measured at the Tevatron and LHC experiments. |
