Revisiting R-invariant Direct Gauge Mediation

High Energy Physics - Phenomenology 2016-04-20 v1

Abstract

We revisit a special model of gauge mediated supersymmetry breaking, the "R-invariant direct gauge mediation." We pay particular attention to whether the model is consistent with the minimal model of the \mu-term, i.e., a simple mass term of the Higgs doublets in the superpotential. Although the incompatibility is highlighted in view of the current experimental constraints on the superparticle masses and the observed Higgs boson mass, the minimal \mu-term can be consistent with the R-invariant gauge mediation model via a careful choice of model parameters. We derive an upper limit on the gluino mass from the observed Higgs boson mass. We also discuss whether the model can explain the 3\sigma excess of the Z+jets+ETmissE_T^{\rm miss} events reported by the ATLAS Collaboration.
