摘要：

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，这为探索中微子特性提供了可能性。我们预测的事件率的增强太阳中微子散射从超越标准模型的相互作用在低阈值DM探测器，重点是硅，锗，砷化镓，氙，氩为基础的探测器。我们考虑一组一般的中微子相互作用，分为五类：中微子磁矩以及介导的四种类型的介质（标量，赝标量，矢量和轴向矢量）的相互作用，并考虑耦合这些介质的夸克或电子。使用这些预测，我们把约束的质量和耦合的每个介质和中微子磁矩从目前的低阈值探测器，如SENSEI，雪绒花，和SuperCDMS，以及预测相关的未来实验，如DAMIC-M，Oscura，达尔文，和ARGO。我们发现，这样的低阈值检测器可以提高电流约束高达两个数量级的矢量介质和一个数量级的标量介质。

英文摘要：

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.
