A New Mechanism for Radius Stabilization in Warped Supersymmetry

TL;DR

This paper proposes a novel mechanism for stabilizing the size of extra dimensions in a warped 5D super-Yang-Mills model, using one-loop quantum effects and Fayet-Iliopoulos terms, resulting in a stabilized radius at an intermediate energy scale.

Contribution

It introduces a new radius stabilization mechanism in warped supersymmetric models based on 1-loop effects and Fayet-Iliopoulos terms, with potential implications for model building.

Findings

Radius stabilized at an intermediate scale of 10^{11-13} GeV.

Effective potential depends on the radion and includes quantum corrections.

Stabilization achieved through a combination of tree-level and quantum effects.

Abstract

A new mechanism for the radius stabilization is proposed in a 5D super-Yang-Mills model in the warped background of ${AdS}_5$. Dominant 1-loop contribution to the supersymmetric 4D effective potential is estimated to depend on the radion. The minimization of the effective potential incorporating the tree potential and a Fayet-Iliopoulos $D$-term for the gauge group U(1) reveals an interesting case that the radius is stabilized at a length corresponding to an intermediate mass scale $10^{11-13}$ GeV.
