本文综述了轻子门暗物质（DM）模型中的唯象现象，其中DM耦合到轻子和额外的轻子/轻子。有几种可能的设置：DM场要么是复数/真实的标量，要么是狄拉克/马约拉纳费米子，耦合到DM的轻子的手征根据DM的自旋而不同。我们讨论了每个模型的预测，并将其与DM检测，LHC和风味实验的最新实验约束进行比较。我们还提出了简单的设置来解决μ子的异常磁矩的差异。
In this paper, we summarize phenomenology in lepton portal dark matter (DM) models, where DM couples to leptons and extra leptons/sleptons. There are several possible setups: a DM field is either a complex/real scalar or a Dirac/Majorana fermion, and chiralities of leptons that couple to the DM are different according to the spin of the DM. We discuss the prediction of each model and compare it with the latest experimental constraints from the DM detections, the LHC, and the flavor experiments. We also propose simple setups to resolve the discrepancy in the anomalous magnetic moment of muon.
