Abstract
The superconformal Ward identities combined with N = 2 harmonic analyticity are used to evaluate two-loop four-point correlation functions of gauge-in variant operators in D = 4, N = 4 supersymmetric Yang-Mills theory in terms of the well-known one-loop box integral. The result is confirmed by a dire ct numerical computation. (C) 1999 Elsevier Science B.V. All rights reserve d.
