4d Yang-Mills theories with extended supersymmetry represent a playground for investigating non-perturbative features and techniques in QFT. Pestun showed that the path integral defining certain protected oservables, both local and non local, localizes to a matrix integral. This great simplification paves the road toward obtaining explicit results at strong coupling and making contact with...

We consider the 4d N=2 SCFT obtained by a Z_2 orbifold of N=4 SYM. By exploiting supersymmetric localization, we determine exact expressions for a broad set of observables, valid at any value of the ’t Hooft coupling in the planar limit of the theory. These observables include two-point and three-point correlation functions between chiral and anti-chiral operators, correlators among Wilson...
