Abstract.

The non-leptonic two body decays \(D\to PP\) and \(D\to PV\) are investigated based on the diagrammatic decomposition in a generalized factorization formalism. It is shown that to fit the experimental data, the SU(3) flavor symmetry breaking effects of the coefficients a i s should be considered in \(D\to PP\) decay modes. In \(D\to PV\) decays, the final state hadron structure due to the pseudoscalar and vector mesons has more important effects on the coefficients a i s than the SU(3) symmetry breaking.
