论文摘要
最近，Xenon1t实验观察到了$ 1 $ - $ 7 $ KEV的电子后坐力数据的过量。最受欢迎的新物理解释之一是电子散射，其速度为$ \ sim 0.1 $，质量为$ \ gtrsim 0.1 \，\ mathrm {mev} $。如果这种粒子与电子具有很强的相互作用，则可能会影响宇宙学的标准情况，或在低阈值直接检测实验中观察到。我们研究各种限制，主要集中于大爆炸核合成，超新星冷却和直接检测实验的限制。我们讨论了这些约束对Xenon1t过量的电子散分解释的含义。
Recently, the XENON1T experiment has observed an excess in the electronic recoil data in the recoil energy range of $1$-$7$ keV. One of the most favored new physics interpretations is electron scattering with a boosted particle with a velocity of $\sim 0.1$ and a mass of $\gtrsim 0.1\,\mathrm{MeV}$. If such a particle has a strong interaction with electrons, it may affect the standard scenario of cosmology or be observed at low-threshold direct detection experiments. We study various constraints, mainly focusing on those from the big-bang nucleosynthesis, supernova cooling, and direct detection experiments. We discuss the implication of these constraints on electron-scattering interpretation of the XENON1T excess.
