# F-term Moduli Stabilization and Uplifting

## TL;DR

This paper introduces a new mechanism for stabilizing K"ahler moduli in IIB superstring theory and demonstrates its effectiveness in uplifting the Large Volume Scenario without destabilizing the vacuum.

## Contribution

It proposes a novel moduli stabilization method using a supersymmetry-breaking chiral superfield coupled in the K"ahler potential, and analyzes its impact on LVS uplift.

## Key findings

- The new mechanism stabilizes K"ahler moduli effectively.
- Uplifting via this method does not destabilize the LVS vacuum.
- The superpotential form is crucial for successful stabilization.

## Abstract

We study K\"ahler moduli stabilization in IIB superstring theory. We propose a new moduli stabilization mechanism by the supersymmetry-braking chiral superfield which is coupled to K\"ahler moduli in K\"ahler potential. We also study uplifting of the Large Volume Scenario (LVS) by it. In both cases, the form of superpotential is crucial for moduli stabilization. We confirm that our uplifting mechanism does not destabilize the vacuum of the LVS drastically.
