Evidence for Large $$N$$ phase transitions in $$N=2^\ast$$ theory

Using localization, we solve for the large-$$N$$ master field of $$N=2^\ast$$ super-Yang-Mills theory and calculate expectation values of large Wilson loops and the free energy. At weak coupling, these observables only receive non-perturbative contributions. The analytic solution holds for a finite range of the 't Hooft coupling and terminates at the point of a large-$$N$$ phase transition. We find evidence that as the coupling is further increased the theory undergoes an infinite sequence of similar transitions that accumulate at infinity.
