AbstractBased on an approximate six-quark operator effective Hamiltonian from perturbative QCD, we present a systematic study of charmless B -> PP, PV, VV decays (P and V denoting pseudoscalar and vector mesons, respectively). The calculation of the relevant hard-scattering kernels is completed; the resulting transition form factors are consistent with the results of QCD sum rule calculation. Important classes of power corrections include 'chirally enhanced' terms, vertex corrections and weak annihilation contributions with a non-trivial strong phase. With these considerations, predictions are presented for the branching ratios and CP asymmetries of B-meson decays into PP, PV and VV final states, and also for the corresponding polarization observables in VV final states. Several decay modes and observables, which are of particular interest phenomenologically, are discussed in detail, including the effect of annihilation amplitude with a strong phase, the pi pi, pi K and pi rho systems, the longitudinal polarization fraction f(L) in rho K* and phi K* systems and so on. It is observed that predictions in our framework generally agree with current experimental data.
