Superconformal operators in Yang–Mills theories on the light-cone Original Research Article

We employ the light-cone superspace formalism to develop an efficient approach to constructing superconformal operators of twist two in Yang–Mills theories with image supercharges. These operators have an autonomous scale dependence to one-loop order and determine the eigenfunctions of the dilatation operator in the underlying gauge theory. We demonstrate that for arbitrary image the superconformal operators are given by remarkably simple, universal expressions involving the light-cone superfields. When written in components field, they coincide with the known results obtained by conventional techniques.
