Abstract

We study two simple and well-motivated nonuniversal gaugino mass models, which predict Higgsino dark matter. One can account for the observed dark matter relic density along with the observed Higgs boson mass of \ensuremath≃125 GeV over a large region of the parameter space of each model, corresponding to a Higgsino mass of \ensuremath≃1 TeV. In each case this parameter region covers the gluino mass range of 2--3 TeV, parts of which can be probed by the 14 TeV LHC experiments. We study these model predictions for the LHC in brief and for dark matter detection experiments in greater detail.
