标题： Anapole moment of neutrinos and radioactive sources near liquid xenon detectors

摘要： 我们证明了在液氙探测器附近放置一个放射性源（例如 ${}^{51}$Cr）可以用来检测由中微子偶极矩引起的中微子-电子散射在标准模型中的贡献。尽管中微子的偶极矩诱导的散射率具有与中性和带电电流贡献相同的光谱形状，但 XENONnT 或 XLZD 中 $\sim$ 10 吨 $\times$ 年的曝光量可能足以积累足够的统计数据。我们还讨论了一个简单的模型，在该模型中中微子的偶极矩相对于标准模型预期值发生了偏移，进一步表明潜在的中微子偶极矩测量结果将有助于限制新物理的存在。 显示英文摘要

摘要： We show that placing a radioactive source such as ${}^{51}$Cr near a liquid xenon detector may allow to detect the contribution induced by the anapole moment to neutrino-electron scattering in the Standard Model. Although the anapole moment of neutrinos induces a scattering rate with the same spectral shape as the neutral and charged current contributions, exposures of $\sim$ 10 tonne $\times$ year at XENONnT or XLZD may be enough to accumulate sufficient statistics. We also discuss a simple model where the anapole moment of neutrinos is shifted with respect to the SM expectation, further demonstrating how a potential measurement of the anapole moment of neutrinos would allow to constrain new physics.
