论文摘要
We continue the study of weakly interacting massive particles (WIMP) started in [arXiv:2107.09688], focusing on a single complex electroweak $n$-plet with non-zero hypercharge added to the Standard Model.深色物质与其电子中性伴侣之间的最小分裂需要绕过直接检测约束,只能使多重负荷较小或等于1的多重组。我们首次计算所有可计算的WIMP质量,最多是扰动单位性允许的最大多重组。对于最小允许的分裂,可以在将来的大型暴露直接检测实验中对这些多重组进行充分探测,而显着的Doublet具有超重1/2。我们展示了未来的MUON对撞机如何充分探索复杂双线的参数空间,结合了缺失的质量,流离失所的轨道和长寿命轨道搜索。本着同样的精神,我们研究了未来的穆恩对撞机如何在直接检测横截面掉落在中微子地面以下的区域中探测复杂wimps的参数空间。最后,我们评论精度可观察物如何在复杂的wimps上提供其他约束。
We continue the study of weakly interacting massive particles (WIMP) started in [arXiv:2107.09688], focusing on a single complex electroweak $n$-plet with non-zero hypercharge added to the Standard Model. The minimal splitting between the Dark Matter and its electroweak neutral partner required to circumvent direct detection constraints allows only multiplets with hypercharge smaller or equal to 1. We compute for the first time all the calculable WIMP masses up to the largest multiplet allowed by perturbative unitarity. For the minimal allowed splitting, most of these multiplets can be fully probed at future large-exposure direct detection experiments, with the notable exception of the doublet with hypercharge 1/2. We show how a future muon collider can fully explore the parameter space of the complex doublet combining missing mass, displaced track and long-lived track searches. In the same spirit, we study how a future muon collider can probe the parameter space of complex WIMPs in regions where the direct detection cross section drops below the neutrino floor. Finally, we comment on how precision observables can provide additional constraints on complex WIMPs.
