有许多标准模型的扩展，预测存在的电弱相互作用的大质量粒子（EWIMPs），特别是在暗物质的背景下。在本文中，我们提供了一种间接研究EWIMP的方法，通过精确研究的对生产过程的带电轻子或带电轻子和中微子在未来的100 TeV对撞机实验。结果表明，这种方法特别适用于Higgsino，为我们提供了在超对称模型中发现Higgsino的5 σ的可能性，其质量可达850 GeV.我们还讨论了如何准确地提取质量，规范电荷，自旋的EWIMP在我们的方法。
There are many extensions of the standard model that predict the existence of electroweakly interacting massive particles (EWIMPs), in particular in the context of the dark matter. In this paper, we provide a way for indirectly studying 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 Higgsino, providing us the $5\sigma$ discovery reach of Higgsino in supersymmetric model with mass up to 850 GeV. We also discuss how accurately one can extract the mass, gauge charge, and spin of EWIMPs in our method.
