摘要:Renewed interest in the spectroscopy of charmonium has arisen from recent unexpected observations
at e+e− colliders. Here we report on a series of works from the previous two years
examining the radiative physics of charmonium states as well as the mass spectrum of states of
higher spin and internal excitation. Using new techniques applied to Domain-Wall and Clover
quark actions on quenched isotropic and anisotropic lattices, radiative transitions and two-photon
decays are considered for the first time. Comparisons are made with experimental results and with
model approaches. Forthcoming application to the light-quark sector of relevance to experiments
like Jefferson Lab’s GlueX is discussed.
