Gravity Mediation of Supersymmetry Breaking with Dynamical Metastability

TL;DR

This paper introduces a new class of dynamical supersymmetry-breaking models that avoid the Polonyi problem by having a vacuum landscape with many supersymmetric vacua, predicting minor deviations from standard big-bang nucleosynthesis.

Contribution

It presents a novel dynamical framework for supersymmetry breaking that circumvents the Polonyi problem and naturally predicts small deviations in nucleosynthesis.

Findings

Polonyi problem can be avoided with multiple supersymmetric vacua

Constructed models demonstrate dynamical supersymmetry breaking

Predicted small deviations from big-bang nucleosynthesis

Abstract

We argue that the Polonyi problem can be avoided when our supersymmetry-breaking vacuum is surrounded by many supersymmetric vacua. We construct a dynamical class of supersymmetry-breaking models to demonstrate our point. These models naturally predict a small deviation from the standard big-bang nucleosynthesis.
