Inflation, moduli (de)stabilization and supersymmetry breaking

TL;DR

This paper explores a hybrid inflation model where the superpotential's value varies to stabilize moduli during inflation and allows for supersymmetry breaking in the true vacuum, providing insights into moduli stabilization in cosmology.

Contribution

It introduces a simple hybrid model demonstrating how superpotential dynamics can achieve moduli stabilization during inflation and supersymmetry breaking afterward.

Findings

Superpotential is large during inflation for moduli stabilization.

Superpotential becomes small in the true vacuum.

The model offers a viable scenario for cosmological inflation with moduli stabilization.

Abstract

We study the cosmological inflation from the viewpoint of the moduli stabilization. We study the scenario that the superpotential has a large value during the inflation era enough to stabilize moduli, but it is small in the true vacuum. This scenario is discussed by using a simple model, one type of hybrid models.
