摘要：We provide the analysis of charmless two-body B!VP decays under the framework of the softcollinear-
effective-theory, where V(P) denotes a light vector (pseudoscalar) meson. Using the
available data, we fit 16 non-perturbative inputs responsible for the B!PP and B!VP decay
channels in the c2 fit method. We find that chiraly enhanced penguins can change several charming
penguins sizably, but most of the other non-perturbative inputs and predictions on branching
ratios and CP asymmetries are not changed too much. We predict the branching fractions and CP
asymmetries of other modes especially Bs!VP decays. The agreements and disagreements with
results in QCD factorization and perturbative QCD approach are analyzed.
