# Supersymmetry breaking metastable vacua in runaway quiver gauge theories

## TL;DR

This paper investigates how adding flavors to quiver gauge theories with fractional branes induces metastable supersymmetry breaking vacua, providing analytic methods to study their stability and extending previous results to more general cases.

## Contribution

It introduces a direct Feynman diagram approach to compute pseudomoduli masses, enabling analytic analysis of metastable vacua in a broad class of DSB brane theories.

## Key findings

- Metastable supersymmetry breaking minima are achievable with added flavors.
- Analytic computation of pseudomoduli masses is possible for general DSB brane theories.
- The approach extends previous results to arbitrary superpotential couplings.

## Abstract

In this paper we consider quiver gauge theories with fractional branes whose infrared dynamics removes the classical supersymmetric vacua (DSB branes). We show that addition of flavors to these theories (via additional non-compact branes) leads to local meta-stable supersymmetry breaking minima, closely related to those of SQCD with massive flavors. We simplify the study of the one-loop lifting of the accidental classical flat directions by direct computation of the pseudomoduli masses via Feynman diagrams. This new approach allows to obtain analytic results for all these theories. This work extends the results for the $dP_1$ theory in hep-th/0607218. The new approach allows to generalize the computation to general examples of DSB branes, and for arbitrary values of the superpotential couplings.
