In natural scenarios of SUSY, top squarks, bottom squarks, gluinos, and higgsino-enriched neutralinos and charginos are expected to be relatively light, enhancing their production cross sections. Higgsino searches have been performed by both the ATLAS and CMS experiments at the Large Hadron Collider at CERN, where physicists have searched for the direct electroweak pair production of Higgsinos. As of March 2014, no experimental evidence for Higginos has been reported.23
If Dark matter is composed only of Higgsinos then the Higgsino mass is 1.1 TeV. On other hand if dark matter has multi-components then the Higgsino mass, depends on the relevant multiverse distribution functions making the mass of the Higgsino lighter.
