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, G_2n^(EFT) = \frac2⁴ⁿZ_S⁴[τ] Γ(2n + 5/2) e^{A[τ]n + B[τ]} with A[τ] and B[τ] given as explicit functions of the coupling constant τ in closed form. 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.
