چکیده    We compute correlation functions of chiral primary operators in $$ mathcal{n}=2 $$ super-conformal theories at large n using a construction based on supersymmetric localization recently developed by gerchkovitz et al. we focus on $$ mathcal{n}=4 $$ sym as well as on supercon-formal qcd. in the case of $$ mathcal{n}=4 $$ we recover the free field theory results as expected due to non-renormalization theorems. in the case of superconformal qcd we study the planar expansion in the large n limit. the final correlators admit a simple generalization to a finite n formula which exactly matches the various small n results in the literature.
