随着低阈值暗物质探测器的发展，它们将对太阳中微子的反冲变得敏感，这为探索中微子的性质打开了可能性。我们预测了低阈值DM探测器中标准模型以外相互作用引起的太阳中微子散射事件率的增强，重点是硅、锗、砷化镓、氙气和氩基探测器。我们考虑了一组一般的中微子相互作用，这些相互作用分为五类：中微子磁矩以及由四种介质(标量、伪标量、矢量和轴矢量)介导的相互作用，并考虑将这些介质耦合到夸克或电子。使用这些预测，我们限制了每个介体的质量和耦合，以及来自当前低阈值探测器(如SENSEI、Edelweiss和SuperCDMS)的中微子磁矩，以及与未来实验相关的预测，如DAMIC-M、Oscura、Darwin和Argo。我们发现，这种低阈值检测器可以改善电流约束，对于矢量介体最高可提高两个数量级，对于标量介体最高可提高一个数量级。
As low-threshold dark matter detectors advance in development, they will become sensitive to recoils from solar neutrinos which opens up the possibility to explore neutrino properties. We predict the enhancement of the event rate of solar neutrino scattering from Beyond the Standard Model interactions in low-threshold DM detectors, with a focus on silicon, germanium, gallium arsenide, xenon, and argon-based detectors. We consider a set of general neutrino interactions, which fall into five categories: the neutrino magnetic moment as well as interactions mediated by four types of mediators (scalar, pseudoscalar, vector, and axial vector), and consider coupling these mediators to either quarks or electrons. Using these predictions, we place constraints on the mass and couplings of each mediator and the neutrino magnetic moment from current low-threshold detectors like SENSEI, Edelweiss, and SuperCDMS, as well as projections relevant for future experiments such as DAMIC-M, Oscura, Darwin, and ARGO. We find that such low-threshold detectors can improve current constraints by up to two orders of magnitude for vector mediators and one order of magnitude for scalar mediators.
