WOLK, Brian Jonathan. An alternative derivation of the Dirac operator generating intrinsic Lagrangian local gauge invariance. Pap. Phys. [online]. 2017, vol.9, n.1. ISSN 1852-4249.  http://dx.doi.org/10.4279/PIP.090002.

This paper introduces an alternative formalism for deriving the Dirac operator and equa-tion. The use of this formalism concomitantly generates a sepárate operator coupled to the Dirac operator. When operating on a Clifford field, this coupled operator produces field components which are formally equivalent to the field components of Maxwell's electro-magnetic field tensor. Consequently, the Lagrangian of the associated coupled field exhibits internal local gauge symmetry. The coupled field Lagrangian is seen to be equivalent to the Lagrangian of Quantum Electrodynamics.
