AI 中文摘要
我们介绍了用于直接探测的太阳中微子（$\texttt{SNuDD}$）：一个开源Python包，可在直接探测实验中计算太阳中微子率谱。$\texttt{SNuDD}$可用于确定标准模型以及存在超出标准模型物理效应（如中性流非标准相互作用产生的效应）时核反冲和电子反冲的微分率。该包考虑了中微子在穿过太阳和地球时的物质效应以及相互作用位点散射截面的修正。我们利用$\texttt{SNuDD}$，根据基于氙的直接探测实验LZ、XENONnT和PandaX - 4T的结果，对有效非标准相互作用耦合设置新的限制，并根据计划中的XLZD和PandaX - xT天文台预测未来氙探测器的灵敏度。我们发现当前直接探测实验正迅速接近与专用中微子实验相当的灵敏度，且未来氙探测器能提供主要限制。我们建议在未来的全局拟合中使用$\texttt{SNuDD}$将传入的直接探测数据与中微子实验数据相结合，将直接探测置于更广阔的中微子物理图景中。
英文摘要
We introduce Solar Neutrinos for Direct Detection ($\texttt{SNuDD}$): an open-source Python package that enables the computation of the solar neutrino rate spectrum at direct detection experiments. $\texttt{SNuDD}$ can be used to determine the differential rate for both nuclear and electron recoils within the Standard Model and in the presence of beyond Standard Model physics effects, such as those arising from neutral-current non-standard interactions (NSI). The package accounts for matter effects during neutrino propagation through both the Sun and the Earth and for modifications to the scattering cross sections at the interaction site. We employ $\texttt{SNuDD}$ to place new limits on the effective NSI couplings using results from the xenon-based direct detection experiments LZ, XENONnT, and PandaX-4T, and we project the sensitivity of a future xenon detector based on the planned XLZD and PandaX-xT observatories. We find that current direct detection experiments are rapidly approaching sensitivities comparable to those of dedicated neutrino experiments and that future xenon detectors can provide leading constraints. We recommend that $\texttt{SNuDD}$ be used to combine incoming direct detection data with those from neutrino experiments in future global fits, placing direct detection within the broader landscape of neutrino physics.
