TL;DR

This paper proposes a generalized anomaly mediation model that naturally explains the muon g-2 anomaly and the Higgs boson mass around 125 GeV, aligning with grand unified theories.

Contribution

It introduces a simple, generalized anomaly mediation framework that accommodates muon g-2 and Higgs mass observations while naturally achieving the necessary SUSY particle mass splittings.

Findings

Model successfully explains muon g-2 anomaly.

Higgs boson mass around 125 GeV is accommodated.

Mass splitting between SUSY particles is naturally achieved.

Abstract

Motivated by two experimental facts, the muon g-2 anomaly and the observed Higgs boson mass around 125 GeV, we propose a simple model of anomaly mediation, which can be seen as a generalization of mixed modulus-anomaly mediation. In our model, the discrepancy of the muon g-2 and the Higgs boson mass around 125 GeV are easily accommodated. The required mass splitting between the strongly and weakly interacting SUSY particles are naturally achieved by the contribution from anomaly mediation. This model is easily consistent with SU(5) or SO(10) grand unified theory.
