On the holographic duals of N=1 gauge dynamics
J. Sonnenschein, A. Loewy
TL;DR
The paper analyzes holographic duals of confining N=1 gauge dynamics through the KS and MN backgrounds, focusing on Wilson loops, flux tubes, ’t Hooft loops, baryons, instantons, chiral symmetry breaking, gluino condensates, and BPS domain walls. It shows how area-law confinement, flux-tube broadening, monopole screening, and domain-wall physics emerge in these models and uses these insights to propose practical guidelines for building new holographic duals via wrapped branes and flux topologies. The work highlights both the successes in capturing key nonperturbative phenomena and the limitations due to KK modes, offering a structured framework for extending holographic descriptions of N=1 dynamics. Overall, it provides a concrete, model-based methodology for mapping 4d nonperturbative N=1 physics onto string-theory backgrounds and guiding future dual constructions.
Abstract
We analyze the holographic description of several properties of $\N=1$ confining gauge dynamics. In particular we discuss Wilson loops including the issues of a Luscher term and the broadening of the flux tubes, 't Hooft loops, baryons, instantons, chiral symmetry breaking, the gluino condensate and BPS domain walls.
