| 英文摘要 | We analyze charmless two-body non-leptonic B decays B -> PP, PV under the framework of a factorization-assisted topological-amplitude approach, where P(V) denotes a light pseudoscalar (vector) meson. Compared with the conventional flavor diagram approach, we consider the flavor SU(3) breaking effect assisted by a factorization hypothesis for topological diagram amplitudes of different decay modes, factorizing out the corresponding decay constants and form factors. The non-perturbative parameters of topology diagram magnitudes (X) and the strong phase phi are universal; they can be extracted by (2)(X) fit from current abundant experimental data of charmless Bdecays. The number of free parameters and the (2)(X) per degree of freedom are both reduced compared with previous analyses. With these best fitted parameters, we predict branching fractions and CP asymmetry parameters of nearly 100 B-u,B-d and B-s decay modes. The long-standing pi pi and pi K-CP puzzles are solved simultaneously. |
