Contribution

It advances the understanding of the N=1 SQCD/string duality by incorporating large N and F regimes, and offers detailed predictions for field theory observables.

Findings

Predicted Seiberg duality and gauge coupling behavior.

Analyzed Wilson and 't Hooft loop behaviors.

Provided evidence for smooth interpolation between vacua.

Abstract

In this paper we make further refinements to the duality proposed between N=1 SQCD and certain string (supergravity plus branes) backgrounds, working in the regime of comparable large number of colors and flavors. Using the string theory solutions, we predict different field theory observables and phenomena like Seiberg duality, gauge coupling and its running, the behavior of Wilson and 't Hooft loops, anomalous dimensions of the quark superfields, quartic superpotential coupling and its running, continuous and discrete anomaly matching. We also give evidence for the smooth interpolation between higgsed and confining vacua. We provide several matchings between field theory and string theory computations.
