Two-Body Cabibbo-Suppressed Charmed Meson Decays

Singly-Cabibbo-suppressed decays of charmed particles governed by the quark subprocesses $c\to su\bar{s}$ and $c\to du\bar{d}$ are analyzed using a flavor-topology approach, based on a previous analysis of the Cabibbo-favored decays governed by $c\to su\bar{d}$. Decays to $PP$ and $PV$, where $P$ is a pseudoscalar meson and $V$ is a vector meson, are considered. We include processes in which $\eta$ and ${\eta }^{\mathrm{\prime }}$ are produced.
