These include new measurements of the M1 radiative transition rates $B(ψ(1S,2S)\toγη_c(1S))$; new insights into the mass of the $η_c(1S)$; the observation of $J/ψ(1S)$ decays to three photons; new measurements of the two-photon widths of the $χ_{cJ}(1P)$; the observation of radiative decays of the $χ_{cj}(1P)$ to light quarks; a precise measurement of the $h_c(1P)$ mass; and an update on properties of the $η_c(2S)$. Each result adds piecemeal to our understanding of the strong force.Submission to the 34th International Conference on High Energy PhysicsHigh Energy Physics - Experimenttext
