论文摘要
我们研究了对低能大气中微子的未来Xenon和基于氩的暗物质和中微子检测实验的敏感性。不考虑实验背景，鉴定由大气中微子引起的核后坐力的主要障碍是由于$ pp $太阳中微子而引起的电子后坐力分布的尾巴。我们使用巢代码对氙气检测器中的太阳和大气中微子信号进行建模，并发现700吨年的暴露将产生$5σ$检测大气中微子的检测。我们探讨了不同检测器特性的效果，发现足够长的电子寿命对于这种测量的成功至关重要。
We study the sensitivity of future xenon- and argon-based dark matter and neutrino detection experiments to low-energy atmospheric neutrinos. Not accounting for experimental backgrounds, the primary obstacle for identifying nuclear recoils induced by atmospheric neutrinos is the tail of the electron recoil distribution due to $pp$ solar neutrinos. We use the NEST code to model the solar and atmospheric neutrino signals in a xenon detector and find that an exposure of 700 tonne-years will produce a $5σ$ detection of atmospheric neutrinos. We explore the effect of different detector properties and find that a sufficiently long electron lifetime is essential to the success of such a measurement.
