Description
In this talk, recent advances in the second order formalism for fermions in gauge theories are studied. This framework has a direct correspondence to the Dirac formalism but allows the description of an anomalous gyromagnetic factor. Besides, due to its close resemblance of scalar theory, this model incorporates naturally fermion self-interactions. The aim of this work is to analyze the one-loop renormalization of the second order formalism for spin 1/2 fermions with arbitrary gyromagnetic factor and self-interaction couplings in QED and QCD.
