The planar limit of N = 2 chiral correlators

A bstract We derive the planar limit of 2- and 3-point functions of single-trace chiral primary operators of N N = 2 SQCD on S 4 , to all orders in the ’t Hooft coupling. In order to do so, we first obtain a combinatorial expression for the planar free energy of a hermitian matrix model with an infinite number of arbitrary single and double trace terms in the potential; this solution might have applications in many other contexts. We then use these results to evaluate the analogous planar correlation functions on ℝ 4 . Specifically, we compute all the terms with a single value of the ζ function for a few planar 2- and 3-point functions, and conjecture general formulas for these terms for all 2- and 3-point functions on ℝ 4 .
