TL;DR

This paper explores the potential for realizing gauge mediated supersymmetry breaking within type IIB string theory compactifications, highlighting the challenges in achieving viable models due to intertwined supersymmetry breaking and modulus stabilization.

Contribution

It analyzes the feasibility of constructing gauge mediated supersymmetry breaking scenarios in string theory compactifications, emphasizing practical difficulties.

Findings

Such scenarios are theoretically possible in principle.

In practice, separating supersymmetry breaking from modulus stabilization is challenging.

Acceptable models are hard to realize due to these intertwined issues.

Abstract

We discuss the possibility of finding scenarios, within type IIB string theory compactified on Calabi-Yau orientifolds with fluxes, for realizing gauge mediated supersymmetry breaking. We find that while in principle such scenarios are not ruled out, in practice it is hard to get acceptable constructions, since typically, supersymmetry breaking cannot be separated from the stabilization of the light modulus.
