A note on four-point correlators of half-BPS operators in N=4 SYM (1408.3527v2)
Published 15 Aug 2014 in hep-th
Abstract: 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.
