Description
The quark gluon vertex is a fundamental quantity in unquenched QCD, where as the "classical" channel, i.e. the spinor structure of $\gamma_\mu$ is related to strong coupling constants $\alpha_s$. Higher order loop correlation would introduce other non-perturbative non-classical structures to the 3-pt correlation function of $\left<\psi\bar\psi A\right>$. In this work, we carried out computation under the complete tensor basis to see whether they are non-negligible or not.
