Soft Supersymmetry Breaking in Anisotropic LARGE Volume Compactifications

TL;DR

This paper investigates how soft supersymmetry breaking terms behave in anisotropic LARGE volume compactifications, revealing potential for third-generation soft term splitting based on brane configurations.

Contribution

It provides a detailed analysis of soft SUSY breaking terms in anisotropic LARGE volume models with different D7 brane wrappings, highlighting new possibilities for scalar mass hierarchies.

Findings

Scalar masses can be parametrically different depending on brane wrapping

Third-generation soft terms may be split from others

Soft terms depend on brane configuration and matter localization

Abstract

We study soft supersymmetry breaking terms for anisotropic LARGE volume compactifications, where the bulk volume is set by a fibration with one small four-cycle and one large two-cycle. We consider scenarios where D7s wrap either a blow-up cycle or the small fibre cycle. Chiral matter can arise either from modes parallel or perpendicular to the brane. We compute soft terms for this matter and find that for the case where the D7 brane wraps the fibre cycle the scalar masses can be parametrically different, allowing a possible splitting of third-generation soft terms.
