Gauge mediation without gravitino problem by virtue of the QCD anomaly

TL;DR

This paper proposes a model where a QCD anomaly-driven axion from dynamical supersymmetry breaking acts as dark matter, naturally generating the QCD anomaly and Higgs mass without gravitino problems.

Contribution

It introduces a minimal dynamical supersymmetry breaking framework with a QCD anomaly that explains dark matter, Higgs mass, and avoids gravitino issues.

Findings

Axion from DSB can be dark matter candidate.

QCD anomaly and V gravitino mass are naturally generated.

Minimal DSB content suffices for observed Higgs mass.

Abstract

We consider the possibility that the Peccei-Quinn charged dynamical supersymmetry breaking (DSB) of m_{3/2}=O(eV) for the Intriligator-Seiberg-Shih model, an axion, converted from a Nambu-Goldstone boson, could become a dark matter candidate, while the QCD anomaly and a sizable \mu value are naturally generated. We also stress that rather minimal DSB content is sufficient to yield the observed mass of the lightest Higgs boson, other than the acceptable soft mass of sparticles in the observable sector.
