We compute two-point functions of chiral operators TrΦ3 in N = 4 SU(N) supersymmetric Yang-Mills theory to the order g4 in perturbation theory. We perform explicit calculations using N = 1 superspace techniques and find that perturbative corrections to the correlators vanish for all N . While at order g2 the cancellations can be ascribed to the nonrenormalization theorem valid for correlators of operators in the same multiplet as the stress tensor, at order g4 this argument no longer applies… CONTINUE READING
