Metastable supersymmetry breaking without scales

TL;DR

This paper presents new models of metastable supersymmetry breaking where all energy scales are generated dynamically, utilizing Seiberg duality and the ISS mechanism, with some quarks emerging as composites from a strongly coupled sector.

Contribution

It introduces models that achieve metastable supersymmetry breaking without explicit scales, relying on strong dynamics and dualities to generate the necessary scales.

Findings

Models exhibit metastable supersymmetry breaking in the IR.

All scales are generated dynamically from a simple UV setup.

Some quark superfields are composites of a strongly coupled sector.

Abstract

We construct new examples of models of metastable D=4 N=1 supersymmetry breaking in which all scales are generated dynamically. Our models rely on Seiberg duality and on the ISS mechanism of supersymmetry breaking in massive SQCD. Some of the electric quark superfields arise as composites of a strongly coupled gauge sector. This allows us to start with a simple cubic superpotential and an asymptotically free gauge group in the ultraviolet, and end up with an infrared effective theory which breaks supersymmetry dynamically in a metastable state.
