Can Inflation Induce Supersymmetry Breaking in a Metastable Vacuum?

TL;DR

This paper explores how gravitational interactions link inflation and supersymmetry breaking, showing that supersymmetry breaking can be dynamically generated at the end of inflation in models with metastable vacua, consistent with gravity mediation.

Contribution

It demonstrates that in supersymmetric hybrid inflation models, the supersymmetry breaking scale is dynamically generated at inflation's end, connecting inflationary dynamics with supersymmetry breaking.

Findings

Supersymmetry breaking scale is generated dynamically at inflation's end.

The model is consistent with gravity mediation.

R-symmetry plays a crucial role in the inflationary framework.

Abstract

We argue that fields responsible for inflation and supersymmetry breaking are connected by gravitational couplings. In view of the recent progress in studying supersymmetry breaking in a metastable vacuum, we have shown that in models of supersymmetric hybrid inflation, where R-symmetry plays an important role, the scale of supersymmetry breaking is generated dynamically at the end of inflation and turns out to be consistent with gravity mediation.
