F-term Stabilization of Odd Axions in LARGE Volume Scenario

TL;DR

This paper investigates the stabilization of odd and even axionic moduli within the LARGE volume scenario, analyzing their scalar potentials and estimating their decay constants and masses using F-term contributions and non-perturbative effects.

Contribution

It provides a detailed analysis of axion stabilization including odd axions, incorporating various non-perturbative effects in the LARGE volume scenario.

Findings

Decay constants and masses of axions are estimated.

F-term contributions from fluxed instantons are crucial for stabilization.

Both even and odd axions are effectively stabilized in this framework.

Abstract

In the context of the LARGE volume scenario, stabilization of axionic moduli is revisited. This includes both even and odd axions with their scalar potential being generated by F-term contributions via various tree-level and non-perturbative effects like fluxed E3-brane instantons and fluxed poly-instantons. In all the cases, we estimate the decay constants and masses of the axions involved.
