摘要：
We calculate the four-point correlation function of half-BPS operators with weights 2, 3, 3, 4 in N - 4 SYM to two-loop order. The OPE of this correlation function provides a nontrivial check of the integrability conjecture for a class of three-point functions formulated in arXiv:1311.6404. Our perturbative calculation exploits the supergraph formalism in N = 2 harmonic superspace.
