Dynamical SUSY Breaking in Meta-Stable Vacua

TL;DR

This paper demonstrates that simple models of N=1 supersymmetric QCD with massive flavors can exhibit long-lived, meta-stable vacua where supersymmetry is dynamically broken, suggesting such phenomena are common in supersymmetric theories and string landscapes.

Contribution

It introduces a straightforward class of models showing meta-stable dynamical supersymmetry breaking using the free-magnetic dual, addressing previous model-building challenges.

Findings

Existence of meta-stable vacua in N=1 SQCD with massive flavors.

Demonstration of supersymmetry breaking in strongly coupled theories.

Implication that broken supersymmetry is generic in field theories and string vacua.

Abstract

Dynamical supersymmetry breaking in a long-lived meta-stable vacuum is a phenomenologically viable possibility. This relatively unexplored avenue leads to many new models of dynamical supersymmetry breaking. Here, we present a surprisingly simple class of models with meta-stable dynamical supersymmetry breaking: N=1 supersymmetric QCD, with massive flavors. Though these theories are strongly coupled, we definitively demonstrate the existence of meta-stable vacua by using the free-magnetic dual. Model building challenges, such as large flavor symmetries and the absence of an R-symmetry, are easily accommodated in these theories. Their simplicity also suggests that broken supersymmetry is generic in supersymmetric field theory and in the landscape of string vacua.
