TL;DR

This paper explores string theory duals of N=1 gauge theories, identifying solutions that exhibit walking behavior and multiple dynamically generated scales related to symmetry breaking and confinement.

Contribution

It introduces a class of string background solutions that model walking gauge theories with multiple scales, linking them to field theory operators.

Findings

Identification of solutions with walking behavior

Evidence for three distinct dynamical scales

Correspondence between scales and field theory operators

Abstract

Within the context of a String Theory dual to N=1 gauge theories with gauge group SU(Nc) and large Nc, we identify a class of solutions of the background equations for which a suitably defined dual of the gauge coupling exhibits the features of a walking theory. We find evidence for three distinct, dynamically generated scales, characterizing walking, symmetry breaking and confinement, and we put them in correspondence with field theory by an analysis of the operators driving the flow.
