# Starobinsky-like inflation in no-scale supergravity Wess-Zumino model with Polonyi term

## TL;DR

This paper introduces a modified no-scale supergravity model incorporating a Polonyi term, enabling successful Starobinsky-like inflation and supersymmetry breaking, with implications for collider detection of SUSY.

## Contribution

It presents a simple modification to the no-scale supergravity Wess-Zumino model that achieves inflation and SUSY breaking with realistic gravitino masses.

## Key findings

- Successful inflation with gravitino mass below 1000 TeV
- SUSY potentially detectable at LHC or FCC
- Model aligns inflationary dynamics with SUSY breaking constraints

## Abstract

We propose a simple modification of the no-scale supergravity Wess-Zumino model of Starobinsky-like inflation to include a Polonyi term in the superpotential. The purpose of this term is to provide an explicit mechanism for supersymmetry breaking at the end of inflation. We show how successful inflation can be achieved for a gravitino mass satisfying the strict upper bound $m_{3/2}< 10^3$ TeV, with favoured values $m_{3/2}\lesssim\mathcal{O}(1)$ TeV. The model suggests that SUSY may be discovered in collider physics experiments such as the LHC or the FCC.
