Instant uplifted inflation: A solution for a tension between inflation and SUSY breaking scale

TL;DR

The paper proposes a simple mechanism that naturally separates the inflation scale from the SUSY breaking scale, addressing the tension between high-scale inflation and low-scale SUSY breaking in string-inspired models.

Contribution

It introduces a novel solution to decouple the inflationary scale from the SUSY breaking scale, overcoming a key challenge in string cosmology models.

Findings

The mechanism allows high-scale inflation without increasing the SUSY breaking scale.

It provides a consistent framework for low-scale SUSY breaking after inflation.

The approach resolves the tension between inflation and SUSY breaking scales in moduli stabilization.

Abstract

The Hubble parameter during the inflationary era must be smaller than the gravitino mass if the moduli are stabilized by the Kachru-Kallosh-Linde-Trivedi mechanism. This condition represents the difficulty to combine the low scale SUSY breaking and the high scale inflation. We propose a simple mechanism which can naturally separate the inflation scale from the SUSY breaking scale today.
