Moduli stabilization and the pattern of sparticle spectra

TL;DR

This paper explores the pattern of low energy sparticle spectra resulting from moduli stabilization scenarios, highlighting the emergence of mirage mediation and mixed-mediation patterns influenced by non-perturbative effects and sequestered supersymmetry breaking.

Contribution

It introduces the concept of mirage mediation pattern in sparticle spectra and analyzes the effects of mixed-mediation scenarios combining moduli, anomaly, and gauge mediations.

Findings

Mirage mediation leads to distinctive sparticle mass patterns.

Anomaly-mediated soft terms become comparable to moduli-mediated ones.

Mixed-mediation scenarios include gauge mediation effects.

Abstract

We discuss the pattern of low energy sparticle spectra which appears in some class of moduli stabilization scenario. In case that light moduli are stabilized by non-perturbative effects encoded in the superpotential and a phenomenologically viable de Sitter vacuum is obtained by a sequestered supersymmetry breaking sector, the anomaly-mediated soft terms become comparable to the moduli-mediated ones, leading to a quite distinctive pattern of low energy spacticle masses dubbed the mirage mediation pattern. We also discuss low energy sparticle masses in more general mixed-mediation scenario which includes a comparable size of gauge mediation in addition to the moduli and anomaly mediations.
