Revisiting instanton corrections to the Konishi multiplet

We revisit the calculation of instanton effects in correlation functions in N= 4 SYM involving the Konishi operator and operators of twist two. Previous studies revealed that the scaling dimensions and the OPE coefficients of these operators do not receive instanton corrections in the semiclassical...
