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

摘要： 我们展示了将一个放射性源（例如 ${}^{51}$ Cr）放置在液氙探测器附近，可能使我们能够在标准模型中检测到由中微子偶极矩引起的中微子-电子散射贡献，达到 1-2 $\sigma$ 精度。 尽管中微子的偶极矩诱导的散射率与中性和带电电流贡献具有相同的光谱形状，但 XENONnT 或 XLZD 上 60 吨 $\sim$ 源运行 $\times$ 的曝光量可能足以积累足够的统计数据以实现检测。 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被增强或减弱，进一步证明了潜在测量中微子偶极矩如何能够限制新物理。 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 at the 1-2 $\sigma$ level. Although the anapole moment of neutrinos induces a scattering rate with the same spectral shape as the neutral and charged current contributions, exposures of $\sim$ 60 tonne $\times$ source run at XENONnT or XLZD may be enough to accumulate sufficient statistics for a detection. We also discuss a simple model where the anapole moment of neutrinos is enhanced or decreased with respect to the SM expectation, further demonstrating how a potential measurement of the anapole moment of neutrinos would allow to constrain new physics.
