A note on four-point correlators of half-BPS operators in N = 4 $$ \mathcal{N}=4 $$ SYM

Abstract: 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.

“…Our two-and three-loop results are presented in the form of two tables where the values of the numerical coefficients in front of the various integrals in (2.16) are listed. Some of the two-loop results in table 1 were obtained in the past through direct Feynman graph calculations [4,9,11,14,21,22]. The three-loop result for the case G 2222 was first obtained in ref.…”
