摘要：

Them are many extensions of the standard model that predict the existence of electroweakly interacting massive particles (EWIMPs), in particular in the context of dark matter. In this paper, we provide a way to indirectly study EWIMPs through the precise study of the pair-production processes of charged leptons or that of a charged lepton and a neutrino at future 100 TeV collider experiments. It is revealed that this search method is suitable in particular for the Higgsino, providing us with a 5 sigma discovery mach in the supersymmetric model with a mass up to 850 GeV. We also discuss how accurately one can extract the mass, gauge charge, and spin of EWIMPs using our method.
