Abstract
We compute the quark–gluon vertex in quenched lattice QCD, in the Landau gauge using an off-shell mean- field -improved fermion action. The complete vertex is computed in two specific kinematical limits, while the Dirac-vector part is computed for arbitrary kinematics. We find a nontrivial and rich tensor structure, including a substantial infrared enhancement of the interaction strength regardless of kinematics.
