Findings

Constructed brane setups for meta-stable vacua in SU(N_c) theories.

Extended constructions to SO/Sp and tensor matter theories.

Analyzed pseudo-moduli stabilization in these configurations.

Abstract

We construct configurations of NS-, D4-, and D6-branes in type IIA string theory, realizing the recently discussed non-supersymmetric meta-stable minimum of 4d N=1 SU(N_c) super-Yang-Mills theories with massive flavors. We discuss their lift to M-theory and the mechanism of pseudo-moduli stabilization. We extend the construction to many other examples of meta-stable minima, including the SO/Sp theories, SU(N_c) with matter in two-index tensor representations, and to a chiral gauge theory.
