论文摘要
除了黑暗扇区的许多其他解释之外，还可以通过太阳中微子散射与电子（标量或矢量）通过电子中微子散射来解释最近的Xenon1T过量。由于仅可观察到后坐力电子，因此可以出现在最终状态下的kev无菌中微子，而不是活跃的中微子。无菌中微子允许伪级中微子解释Xenon1t的过量，这是不可能的。另外，非零后坐力下微中微子质量产生，可用于证明无菌中微子是否质量大。我们还简要讨论了与Light $ z'$介体的无菌中微子最终状态的案例。
The recent Xenon1T excess can be explained by solar neutrino scattering with electron via a light mediator, either scalar or vector, in addition to many other explanations from the dark sector. Since only the recoil electron is observable, a keV sterile neutrino instead of an active neutrino can appear in the final state. The sterile neutrino allows pseudoscalar mediator to explain the Xenon1T excess which was thought impossible. In addition, nonzero recoil energy lower bound arises from the sterile neutrino mass, which can be used to testify if the sterile neutrino is massive or not. We also briefly discuss the case of a sterile neutrino final state with light $Z'$ mediator.
