A natural renormalizable model of metastable SUSY breaking

TL;DR

This paper introduces a simple, fully dynamical model of metastable supersymmetry breaking where all scales are generated through dimensional transmutation, avoiding fundamental parameters and higher-dimensional operators.

Contribution

It presents a novel variant of the Intriligator-Seiberg-Shih model with all scales generated dynamically via renormalizable couplings, enhancing theoretical simplicity and naturalness.

Findings

All scales are generated dynamically without fundamental parameters.

The model is a simple variant of the ISS model with renormalizable couplings.

No reliance on higher-dimensional operators or explicit mass scales.

Abstract

We propose a model of metastable dynamical supersymmetry breaking in which all scales are generated dynamically. Our construction is a simple variant of the Intriligator-Seiberg-Shih model, with quark masses induced by renormalizable couplings to an auxiliary supersymmetric QCD sector. Since all scales arise from dimensional transmutation, the model has no fundamental dimensionful parameters. It also does not rely on higher-dimensional operators.
