Findings

Geometries depend on Nf/Nc ratio and exhibit good singularities.

Supports field theory interpretation through R-symmetry breaking, instantons, and Wilson loops.

Analyzes a family of solutions dual to N=1 SYM with UV completion.

Abstract

We construct supergravity plus branes solutions, which we argue to be related to 4d N=1 SQCD with a quartic superpotential. The geometries depend on the ratio Nf/Nc which can be kept of order one, present a good singularity at the origin and are weakly curved elsewhere. We support our field theory interpretation by studying a variety of features like R-symmetry breaking, instantons, Seiberg duality, Wilson loops and pair creation, running of couplings and domain walls. In a second part of this paper, we address a different problem: the analysis of the interesting physics of different members of a family of supergravity solutions dual to (unflavored) N=1 SYM plus some UV completion.
