Anatomy of Non-Leptonic Two-Body Decays of Charmed Mesons into Final
States with $\eta'$
We show that $D\rightarrow P\eta'$ decay amplitudes, where $P=K,\pi,\eta$, cannot be simply related to their $D\rightarrow P\eta$ counterparts with a single $\eta_0$--$\eta_8$ mixing angle. Proposing a novel, consistent treatment of $\eta_0$--$\eta_8$ mixing, we perform a global analysis of $D\rightarrow P\eta'$ decays employing SU(3)$_F$ symmetry including linear SU(3)$_F$ breaking. We find …
