Evidence for Large-N Phase Transitions in N=2* Theory

Understand

We solve, using localization, for the large-N master field of N=2* super-Yang-Mills theory.

• From that we calculate expectation values of large Wilson loops and the free energy on the four-sphere.
• 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.
