Abstract 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 Scenarino #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 O ( 1 ) keV. The dark matter, aided by the new gauge interaction, efficiently heats up a neutron star in our Galaxy more than ∼1500 K as a neutron star captures the halo dark matter. Therefore, we propose to utilize the future infrared telescope to test our scenario.

轻子新力和宇宙射线增强了 XENON1T 过剩的暗物质

摘要 最近报道的 XENON1T 过量是由新的轻子力解释的，它没有规范异常。我们专注于有和没有暗物质的两种情况。在场景 #1 中，规范的轻子数 U(1) L e − L j , j = μ 或 τ 的规范玻色子提供了太阳中微子和电子之间的非标准相互作用，从而增加了 XENON1T 探测器中电子反冲事件的数量。在场景#2 中，新规范玻色子只与电子和暗物质耦合，然后宇宙射线电子可以将它们的动量传递给光晕中的暗物质。增强的暗物质产生 O ( 1 ) keV 的电子反冲信号。暗物质在新的规范相互作用的帮助下，有效地将我们银河系中的中子星加热到超过 1500 K，因为中子星捕获了晕暗物质。所以，
