On instanton effects in the operator product expansion

We revisit the computation of instanton effects to various correlation functions in N=4N=4 SYM and clarify a controversy existing in the literature regarding their consistency with the OPE and conformal symmetry. To check these properties, we examine the conformal partial wave decomposition of fou...
