Abstract
We recalculate the branching ratio and asymmetry for decays in the perturbative QCD approach. In this approach, we consider all the possible diagrams including nonfactorizable contributions and annihilation contributions. We obtain . Our result is in agreement with the latest measured branching ratio of by the Belle and HFAG collaborations. We also predict large direct asymmetry and mixing asymmetry in decays, which can be tested by the coming Belle-II experiments.
