Abstract
We calculate the three-loop gauge p-function for an abelian N = 1 supe rsymmetric gauge theory, using DRED. We construct a coupling constant redefinition that relates the result to the corresponding term in the NSVZ beta-function, and by generalising this redefinition to the non-a belian case we derive the DRED three-loop gauge beta-function for the non-abelian case.
