论文摘要
最近报道的新生1T的过量是由新的松性力解释的，后者没有规格异常。我们专注于有和没有暗物质的两种情况。在方案＃1中，量表Lepton编号U（1）$ _ {L_E-L_J} $，$ J =μ$或$τ$提供了Solar Neutrino和Electron之间的非标准相互作用，从而增强了XENON1T检测器中电子后坐力事件的数量。在方案＃2中，新的量规玻色子仅对电子和暗物质，然后宇宙射线电子可以将其动量转移到Halo中的暗物质。增强的暗物质会生成$ {\ cal o}（1）$ kev的电子后坐信号。在新的量规互动的帮助下，暗物质在我们的星系中有效地加热了一个超过$ \ sim1500 $ k的中子星，作为中子星，捕获了晕黑物质。因此，我们建议利用未来的红外望远镜来测试我们的情况。
The recently reported excess in XENON1T is explained by new leptonic forces, which are free from gauge anomalies. We focus on two scenarios with and without dark matter. In Scenario #1, the gauge boson of gauged lepton number U(1)$_{L_e-L_j}$, $j=μ$ or $τ$ provides non-standard interaction between solar neutrino and electron that enhances the number of electron recoil events in the XENON1T detector. In Scenario #2, the new gauge boson exclusively couples to electron and dark matter, then cosmic-ray electrons can transfer their momenta to dark matter in halo. The boosted dark matter generates the electron recoil signals of ${\cal O}(1)$ keV. The dark matter, aided by the new gauge interaction, efficiently heats up a neutron star in our Galaxy more than $\sim1500$ K as a neutron star captures the halo dark matter. Therefore, we propose to utilize the future infrared telescope to test our scenario.
