A 125 GeV Higgs Boson Mass and Gravitino Dark Matter in R-invariant Direct Gauge Mediation

TL;DR

This paper demonstrates that in an R-invariant direct gauge mediation model with a gravitino mass around 1 keV, it is possible to naturally achieve a Higgs boson mass of approximately 125 GeV, consistent with experimental observations.

Contribution

The study introduces a model linking a 125 GeV Higgs mass with keV-scale gravitino dark matter within R-invariant direct gauge mediation, providing a viable scenario for warm dark matter.

Findings

Higgs mass around 125 GeV is achievable in the model.

Gravitino with keV mass can serve as warm dark matter.

Model aligns with LHC Higgs measurements.

Abstract

We discuss the SM-like Higgs boson mass in the MSSM in an R-invariant direct gauge mediation model with the gravitino mass in the O(1) keV range. The gravitino dark matter scenario in this mass range is a good candidate for a slightly warm dark matter. We show that the Higgs boson mass around 125 GeV suggested by the ATLAS and CMS experiments can be easily achieved in the direct gauge mediation model with this gravitino mass range.
