TL;DR

This paper introduces a supergravity-based gauge mediation model with uplifted metastable SUSY breaking, addressing moduli stabilization, SUSY breaking, and gaugino mass generation, while resolving the Landau pole problem.

Contribution

It presents a novel gauge mediation model integrating supergravity effects with uplifted metastable SUSY breaking, ensuring realistic mass spectra and addressing the Landau pole issue.

Findings

Gaugino masses are generated at leading order, comparable to sfermion masses.

The model effectively stabilizes moduli and breaks SUSY and R-symmetry.

Landau pole problem is mitigated by heavy messenger particles.

Abstract

We propose a direct gauge mediation model based on an uplifted metastable SUSY breaking coupled to supergravity. A constant superpotential plays an essential role to fix the moduli as well as breaking SUSY and R-symmetry and the cancellation of the cosmological constant. Gaugino masses are generated at leading order of SUSY breaking scale, and comparable to the sfermion masses as in the ordinary gauge mediation. Landau pole problem for QCD coupling can be easily solved since more than half of messengers become superheavy, which are heavier than the GUT scale.
