Description
We propose an integrability approach for planar three-point functions at finite coupling in N=2 superconformal field theories obtained as Z_K orbifolds of N=4 super Yang-Mills (SYM). Generalising the hexagon formalism for N=4 SYM, we reproduce the structure constants of Coulomb branch operators, previously obtained by supersymmetric localisation, as exact functions of the 't Hooft coupling. Our analysis explains the common physical origin of Fredholm kernels in integrability and localisation, and hints at structures after the resummation in the hexagon formalism. This talk is based on arXiv:2503.07295 written with S. Komatsu and D. Serban.
