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.

Finite width effects in nonleptonic D-decays

Including final-state meson widths in the phase space of nonleptonic D decays changes some flavor-SU(3) branching-ratio predictions, most notably boosting D0 to K*0 eta' far above the experimental upper limit.
