Abstract
We analyze the charmless two-body decays in the soft-collinear-effective-theory (SCET), where denotes a light vector (pseudoscalar) meson. Using the current experimental data, we find two solutions in fit for the 16 non-perturbative inputs responsible for the 87 and 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.
