T-duality of large N QCD

Abstract

We argue that non-supersymmetric large N QCD compactified on T^2 exhibits properties characteristic of an SL(2,Z) T-duality. The kahler structure on which this SL(2,Z) acts is given by $m/N+i{\Lambda }^{2}A$, where A is the area of the torus, m is the 't Hooft magnetic flux on the torus, and ${\Lambda }^2$ is the QCD string tension.
