On instanton effects in the operator product expansion

Abstract:

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 four-point correlators involving combinations of half-BPS and Konishi operators and isolate the contribution from the conformal primary scalar operators of twist four. We demonstrate that the leading ...
