标题： Prospects for Exploring Non-Standard Neutrino Properties with Argon-Based CEvNS Experiments

摘要： 相干弹性中微子-核散射（CEvNS）为在低能下测试标准模型（SM）和寻找新物理提供了一个强大的框架。 在本工作中，我们研究了在停止介子源上基于氩的CEvNS实验在精确测量弱相互作用和探测非标准中微子性质方面的前景。 我们的研究集中在橡树岭国家实验室散裂中子源处的CENNS-10和CENNS-750探测器，洛斯阿拉莫斯国家实验室的Coherent Captain Mills（CCM）探测器，以及费米实验室暗物质发现设施（F2D2）提出的PIP2-BD探测器。 使用对应于这些设施的真实中微子通量和探测器配置，我们评估了事件率和对一系列可观测值的敏感性。 在标准模型范围内，基于氩的CEvNS探测器能够在远低于电弱尺度的动量转移下对电弱参数进行精确测试，包括弱混合角。 我们还研究了这些实验对中微子电磁性质的敏感性，例如磁矩和有效电荷半径，以及对可能的与夸克的非标准中微子相互作用的敏感性。 这些研究共同突显了基于氩的CEvNS实验作为精确探索非标准中微子性质的干净且多功能平台的潜力。 显示英文摘要

摘要： Coherent elastic neutrino-nucleus scattering (CEvNS) provides a powerful framework for testing the Standard Model (SM) and searching for new physics at low energies. In this work, we examine the prospects for argon-based CEvNS experiments at stopped-pion sources to perform precision measurements of weak interactions and probe non-standard neutrino properties. Our study focused on the CENNS-10 and CENNS-750 detectors at the Spallation Neutron Source at Oak Ridge National Laboratory, the Coherent Captain Mills (CCM) detector at Los Alamos National Laboratory, and the proposed PIP2-BD detector at Fermilabs Facility for Dark Matter Discovery (F2D2). Using realistic neutrino fluxes and detector configurations corresponding to these facilities, we evaluate event rates and sensitivities to a range of observables. Within the SM, argon-based CEvNS detectors enable precision tests of electroweak parameters, including the weak mixing angle, at momentum transfers well below the electroweak scale. We also investigate the sensitivity of these experiments to neutrino electromagnetic properties, such as the magnetic moment and effective charge radius, as well as to possible non-standard neutrino interactions with quarks. Together, these studies highlight the potential of argon-based CEvNS experiments as a clean and versatile platform for precision exploration of non-standard neutrino properties.
