The $\eta^\prime g^* g^{(*)}$ Vertex Including the $\eta^\prime$-Meson Mass
The $\eta^\prime g^* g^{(*)}$ effective vertex function (EVF) is calculated in the QCD hard-scattering approach, taking into account the $\eta^\prime$-meson mass. We work in the approximation in which only one non-leading Gegenbauer moment in both the quark-antiquark and gluonic light-cone distribut...
