Proposes new photon line shape and branching fraction extraction method for J/psi to gamma eta_c, claiming compatibility between PDG data correlations and lattice QCD widths via profile scan.
Light-front quark model calculations with two Gaussian wave functions yield transverse mechanical distributions for pseudoscalar charmonium and bottomonium, showing a nodal pressure and positive force.
