Abstract

We analyze the charmless two-body BVPB\to VP decays in the soft-collinear-effective-theory (SCET), where V(P)V(P) denotes a light vector (pseudoscalar) meson. Using the current experimental data, we find two solutions in χ2\chi^2 fit for the 16 non-perturbative inputs responsible for the 87 BPPB\to PP and BVPB\to VP decay channels in SU(3) symmetry. Chirally enhanced penguins can only change several charming penguins sizably, since they share the same topology. The (S-P)(S+P) annihilation penguins in the perturbative QCD approach have the same topology with charming penguins in SCET, which play an important role in direct CP asymmetries.
