Abstract:
We discuss recent progress in the determination of correlators of chiral primary operators in N=4 Super-Yang-Mills theory, based on a combination of superconformal covariance arguments in N=2 harmonic superspace, and Intriligator's insertion formula. Applying this technique to the calculation of the supercurrent four - point function we obtain a compact and explicit result for its three-loop contribution with comparatively little effort.
