The $\eta^{'} g^{*} g^{(*)}$ Vertex Including the $\eta^{'}$-Meson Mass

The $eta^prime g^* g^{(*)}$ effective vertex function 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 for both the quark-antiquark and the gluonic light-cone distribution a...
