Higgsino Dark Matter in Nonuniversal Gaugino Mass Models

Understand

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 ~ 125 GeV over a large region of the parameter space of each model, corresponding to higgsino mass of ~ 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 LHC in brief and for dark matter detection experiments in greater detail.
