在本文中，我们研究了电子味狄拉克暗物质与两种类型的门户相互作用的现象。我们分析了电子磁矩异常、LHC对单电荷标量的搜索、暗物质遗迹丰度以及直接和间接探测等方面的限制。我们的研究表明，可用的参数空间是相当有限的，但有参数空间是兼容的当前数据。我们进一步表明，DAMPE宇宙射线电子过剩，这表明宇宙射线过剩在1.5 TeV左右，可以解释为湮灭的暗物质成电子正电子对在这个模型中。
In this paper we investigate the phenomenology of the electron flavored Dirac dark matter with two types of portal interactions. We analyze constraints from the electron magnetic moment anomaly, LHC searches of singly charged scalar, dark matter relic abundance as well as direct and indirect detections. Our study shows that the available parameter space is quite constrained, but there are parameter space that is compatible with the current data. We further show that the DAMPE cosmic ray electron excess, which indicates cosmic ray excess at around 1.5 TeV, can be interpreted as the annihilation of dark matter into electron positron pairs in this model.
