Dynamically sequestered F-term uplifting in extra dimension

TL;DR

This paper presents a supergravity model with an extra dimension that dynamically achieves moduli stabilization, SUSY breaking, and sequestering, resulting in suppressed scalar masses and mirage gaugino masses.

Contribution

It introduces a simple supergravity framework with wavefunction localization for sequestering, explicitly deriving soft SUSY breaking terms and stabilizing the radius modulus.

Findings

Scalar masses and A-terms are suppressed at the Minkowski minimum.

Gaugino masses exhibit a mirage pattern.

The model explicitly demonstrates moduli stabilization and SUSY breaking in extra dimensions.

Abstract

We study concretely several issues altogether, moduli stabilization, the dynamical supersymmetry (SUSY) breaking, the uplifting of SUSY anti-de Sitter (AdS) vacuum and the sequestering of hidden sector, in a simple supergravity model with a single extra dimension. The sequestering is achieved dynamically by a wavefunction localization in extra dimension. The expressions for the visible sector soft SUSY breaking terms as well as the hidden sector potential are shown explicitly in our model. We find that the tree-level soft scalar mass and the A-term can be suppressed at a SUSY breaking Minkowski minimum where the radius modulus is stabilized, while gaugino masses would be a mirage type.
