Abstract

We analyze the decay modes of $D/D_s\to PP,PV$ on the basis of a hybrid method with the generalized factorization approach for emission diagrams and the pole dominance model for the annihilation type contributions. Our results of PV final states are better than the previous method, while the results of PP final states are comparable with previous diagrammatic approach.
