In this presentation, we apply the similar idea of Fierz rearrangement to the electromagnetic processes and focus on the electromagnetic form factors of nucleon and electron. We explain the motivation of using four-fermion operators and discuss the advantage of this method in computing electromagnetic processes.}, number={9}, journal={PHYSICAL REVIEW D}, author={Ji, Chueng-Ryong and Bakker, Bernard L.

Research in this field over the years has shown us that mathematical consistency only is not enough to guarantee physically meaningful results. Whatever the prescription invoked to handle such an object, it has to preserve causality in the process. On the other hand, the covariantization technique is a well-suited one to tackle gauge-dependent poles in the Feynman integrals, dispensing the use of ad hoc prescriptions. In this work we show that the covariantization technique in the light-cone gauge is a direct consequence of the canonical quantization of the theory. }, number={19}, journal={MODERN PHYSICS LETTERS A}, author={Suzuki, AT}, year={2005}, month={Jun}, pages={1459–1464} }
 @article{suzuki_sales_2004, title={Quantum gauge boson propagators in the light front}, volume={19}, ISSN={["0217-7323"]}, DOI={10.1142/S021773230401566X}, abstractNote={ Gauge fields in the light front are traditionally addressed via the employment of an algebraic condition n·A=0 in the Lagrangian density, where Aμ is the gauge field (Abelian or non-Abelian) and nμ is the external, light-like, constant vector which defines the gauge proper. However, this condition though necessary is not sufficient to fix the gauge completely; there still remains a residual gauge freedom that must be addressed appropriately. To do this, we need to define the condition (n·A)(∂·A)=0 with n·A=0=∂·A. The implementation of this condition in the theory gives rise to a gauge boson propagator (in momentum space) leading to conspicuous nonlocal singularities of the type (k·n)-α where α=1,2. These singularities must be conveniently treated, and by convenient we mean not only mathemathically well-defined but physically sound and meaningful as well. In calculating such a propagator for one and two noncovariant gauge bosons those singularities demand from the outset the use of a prescription such as the Mandelstam–Leibbrandt (ML) one. We show that the implementation of the ML prescription does not remove certain pathologies associated with zero modes. However we present a causal, singularity-softening prescription and show how to keep causality from being broken without the zero mode nuisance and letting only the propagation of physical degrees of freedom. }, number={38}, journal={MODERN PHYSICS LETTERS A}, author={Suzuki, AT and Sales, JHO}, year={2004}, month={Dec}, pages={2831–2844} }

This is accomplished via (n·A)2+(∂·A)2 terms in the Lagrangian density.
