Motivated by extensive new high-precision experimental data, we present an updated analysis of the two-body charm decays $D \to PV$ (with $P =\pi,K, \eta^{(\prime)}$ and $V =\rho, K^*, \omega, \phi$) within the factorization-assisted…

The non-$D \bar D$ decays of the $\ppp = \psi(3770)$ resonance are reviewed and possibilities for further measurements are noted. These decays can shed light on S--D mixing, the ``missing'' $\psi' = \psi(3686)$ decays, a possible…
