abstract
The coupling of various charmonium mesons to a photon is studied using lattice QCD, giving access to radiative form factors and transitions, and probing the mesons' structure. Methods are developed which allow the robust determination of amplitudes, including those involving an excited state as well as multiple form factors, for a range of kinematics. These are applied in dynamical lattice QCD calculations using the distillation technique to compute the underlying three-point correlation functions. Form factors and amplitudes involving the low-lying charmonia, $\eta_c$, $J/\psi$, $\chi_{c0}$ and $\eta_c'$, are calculated, demonstrating the methods and providing the first dynamical lattice QCD results for some quantities.

$\eta$ and $\eta'$ production in $J/\psi$ radiative decays from quantum chromodynamics
The first 2+1 flavor lattice QCD calculation of J/psi to gamma eta and gamma eta' form factors finds an enhanced eta'/eta ratio but absolute rates below experiment at m_pi around 391 MeV.

$\eta$ and $\eta'$ meson production in $J/\psi$ radiative decays from lattice QCD
A 2+1 flavor lattice QCD calculation determines the J/psi to gamma eta and J/psi to gamma eta' transition form factors separately for the first time, finding rates below experiment.

Radiative decays $J/\psi,\,\psi(2S)\rightarrow\gamma\eta^{(\prime)}$ in perturbative QCD with relativistic corrections
Order-q² relativistic corrections in pQCD roughly double J/ψ→γη(') rates and favor a smaller mixing angle, while ψ(2S) rates overshoot data and may require coherent ηc mixing.

A Unified Study of Hidden-Charm and Hidden-Bottom Mesons
A common screened-potential and QCD sum-rule framework yields consistent spectra, E1/M1 widths, Regge slopes, decay constants and finite-spectrum thermal indicators for c¯c and b¯b mesons.
