Flavor $SU(3)$ in Cabibbo-favored $D$-meson decays

Abstract

Model-independent description of nonleptonic decays of charmed mesons is a challenging task due to large nonperturbative effects of strong interactions on the transition amplitudes. We discuss the equivalence of two different flavor-$SU(3)$-based descriptions of Cabibbo-favored non-leptonic decays of charmed mesons to two-pseudoscalars final states including the $\eta$ and $\eta^\prime$ mesons.
