Abstract
In this work, the renormalization of the second-order QCD is analyzed at one-loop level, including an arbitrary chromomagnetic factor and quark self-interactions, which are mass dimension four operators in this framework. The model is shown to be renormalizable for any value of the chromomagnetic factor in the validity region of the perturbative expansion, and Dirac QCD is recovered in the case with vanishing self-interaction couplings.
