SU(3)-Flavor-Analysis of Nonfactorizable Contributions to $D \to Pp$ Decays

Abstract

We study charm D - meson decays to two pseudoscalar mesons in Cabibbo favored mode employing SU(3)-flavor for the nonfactorizable matrix elements. Using $D\rightarrow \bar K \pi$ and $D_{s} \rightarrow \bar K K$ to fix the reduced matrix elements, we obtain a consistent fit for $ \eta$ and $ \eta'$ emitting decays of $D$ and $ D_{s}$ mesons.
