Large $N$ reduction in deformed Yang-Mills theories

Abstract

We explore, at the nonperturbative level, the large $N$ equivalence between ordinary $SU(N)$ Yang-Mills theory on ${\mathbb{R}}^4$ and on ${\mathbb{R}}^3\times S^1$ with double-trace deformations. In particular, we compare the values of the $0^{++}$ glueball mass obtained in both sides of the equivalence.
