电弱相互作用大质量粒子（EWIMPs）存在于标准模型之外的一大类新物理模型中。寻找这样的粒子是LHC和未来对撞机的主要目标之一。EWIMP通常通过量子修正影响LHC签名，即使没有直接产生。通过精确测量标准模型过程，我们可以间接探测EWIMP。本文利用强子对撞机上带电Drell-Yan过程产生单轻子的精确测量结果，研究了EWIMP的当前约束和未来前景。从中性Drell-Yan过程中我们发现单轻子签名比双轻子签名更能作为一种更好的探针。
Electroweak-interacting massive particles (EWIMPs) exist in a broad class of new physics models beyond the Standard Model. Searching for such particles is one of most primary goal at the LHC and future colliders. The EWIMP generally affects the LHC signatures through quantum corrections even without direct productions. By measuring the Standard Model processes precisely, we can indirectly probe the EWIMPs. In this paper, we study the current constraint and future prospect of the EWIMPs by using the precision measurements of mono-lepton production from the charged Drell-Yan processes at hadron colliders. We found the mono-lepton signature can be a better probe than dilepton signature from the neutral Drell-Yan processes.
