# Large R-charge EFT correlators in N=2 SQCD

### Abstract

We consider large-R-charge Coulomb branch correlation functions in N=2 superconformal QCD in D=4 dimensions, with gauge group SU(2) and $N_f = 4$ hypermultiplets in the fundamental representation. Using information from supersymmetric recursion relations, S-duality, and matching of EFT parameters with the double-scaling limit, we give an exact formula for the massless Coulomb branch EFT contribution to the correlation function two-point functions of the n-th power of the chiral ring generator. We note the precise agreement of the EFT formula with supersymmetric localization even at low values of n, and discuss aspects of the post-EFT remainder contributed by the macroscopic virtual propagation of massive particles
