Muon g-2 in MSSM Gauge Mediation Revisited

, and .
(Apr 3, 2017)

Abstract

The Higgs boson of 125 GeV requires large stop masses, leading to the large \$\mu\$-parameter in most cases of gauge mediation. On the other hand, the explanation for the muon g-2 anomaly needs small slepton and neutralino/chargino masses. Such disparity in masses may be obtained from a mass splitting of colored and non-colored messenger fields. However, even if the required small slepton and neutralino/chargino masses are realized, all parameter regions consistent with the muon g-2 are excluded by the recent updated ATLAS result on the wino search. We show, giving a simple example model, that the above confliction is solved if there is an additional contribution to the Higgs soft mass which makes the \$\mu\$-parameter small.
