论文摘要
我们研究了检测器对相干弹性中微子核散射（CE $ν$ ns）的灵敏度的灵敏度，以及这些检测器如何补充核后坐力能量的测量值。我们考虑停止锥形和反应堆中微子来源，并使用气态氦气和氟作为检测器材料的例子。我们生成标准模型预测，并与包括新的，光线或标量介质的方案进行比较。我们表明，方向检测器可以在辨别新物理学方面提供有价值的其他信息，并且我们在光介质的角度和后坐力能量光谱中都确定了显着的光谱特征，即使是核后坐力阈值高达$ \ sim 50 $ kev。结合能量和计时信息，定向信息可以在从CE $ν$ ns实验中提取新物理学方面发挥重要作用。
We study the sensitivity of detectors with directional sensitivity to coherent elastic neutrino-nucleus scattering (CE$ν$NS), and how these detectors complement measurements of the nuclear recoil energy. We consider stopped pion and reactor neutrino sources, and use gaseous helium and fluorine as examples of detector material. We generate Standard Model predictions, and compare to scenarios that include new, light vector or scalar mediators. We show that directional detectors can provide valuable additional information in discerning new physics, and we identify prominent spectral features in both the angular and the recoil energy spectrum for light mediators, even for nuclear recoil energy thresholds as high as $\sim 50$ keV. Combined with energy and timing information, directional information can play an important role in extracting new physics from CE$ν$NS experiments.
