CLFQM calculations of D(s) to P/S/V/A form factors and branching ratios agree with data for most P and V channels but show notable discrepancies for several S and A channels.

abstract
We present an improved light-cone sum rule analysis of the decay form factors of $D$ and $D_s$ into $\eta$ and $\eta^{\prime}$ and argue that these decays offer a very promissing possibility to determine the leading Fock-state gluonic contribution of the $\eta'$ at future experimental facilities as FAIR or Super-KEKB. We also give the corresponding branching ratios for B decays.

A review of BESIII charmed meson decay studies presents the most precise averages for |V_cs|, |V_cd|, D and D_s decay constants, and several hadronic form factors from combined experimental results.
