General calculation of theN=4supersymmetric Yang-Mills self-energy in an effective light-cone gauge formalism

Abstract
The N=4 supersymmetric Yang-Mills self-energy is calculated, to one-loop order, in a light-cone gauge that respects power counting and locality of the integrals. The calculation is general, including both physical and unphysical modes (fields). It is found that the self-energy satisfies the Ward identity and that is is infrared finite, but ultraviolet divergent.
