论文摘要
对暗物质电子散射横截面的新Xenon1t观察以及进一步限制了许多流行的暗物质模型，表明在低能量下新物理学的可能性。我们指出，这种新的观察结果还显着限制了中微子非标准相互作用（NSI）。我们认为由动力学混合的$ z'$与活跃和轻质无菌中微子的肾小函数和偶极样相互作用产生的NSI。顺便说一句，我们还解决了在存在这种NSI存在下电子后坐力〜2 keV周围Xenon1t过量的可能性。
The new XENON1T observation of dark matter-electron scattering cross-section, along with further constraining many popular dark matter models, has indicated the possibility of new physics at a low energy. We point out that this new observation also significantly constrain the neutrino non-standard interactions (NSI). We consider the NSI arising from a kinetically mixed $Z'$ with renormalisable and dipole-like interactions with the active and light sterile neutrinos. In passing, we also address the possibility of explaining the XENON1T excess around electron recoil energy ~ 2 keV in presence of such NSI.
