Anomalous dimensions in N=4 SYM theory at order g^4
arXiv:hep-th/0003203 · doi:10.1016/S0550-3213(00)00312-6
Abstract
We compute four-point correlation functions of scalar composite operators in the N=4 supercurrent multiplet at order g^4 using the N=1 superfield formalism. We confirm the interpretation of short-distance logarithmic behaviours in terms of anomalous dimensions of unprotected operators exchanged in the intermediate channels and we determine the two-loop contribution to the anomalous dimension of the N=4 Konishi supermultiplet.
