论文摘要
中微子磁力和电力矩在树的水平上为零，但可以在辐射校正中出现。除标准模型预测的任何偏差都将为中微子相关的新物理学提供另一种迹象，除了中微子振荡和质量。尤其是，狄拉克（Dirac）和主要中微子在电磁矩中具有完全不同的结构。然而，后坐力测量和天体物理恒星冷却只能限制中微子磁和电矩的组合，而没有看到它们的详细结构。我们建议使用中微子对的原子辐射发射作为中微子电磁力矩的独特探针，不仅可以分开磁性和电力矩，还可以识别其各个元素。这封信中说明了搜索策略和预计敏感性。
The neutrino magnetic and electric moments are zero at tree level but can arise in radiative corrections. Any deviation from the Standard Model prediction would provide another indication of neutrino-related new physics in addition to the neutrino oscillation and masses. Especially, Dirac and Majorana neutrinos have quite different structures in their electromagnetic moments. Nevertheless, the recoil measurements and astrophysical stellar cooling can only constrain combinations of neutrino magnetic and electric moments with the limitation of not seeing their detailed structures. We propose using the atomic radiative emission of neutrino pair to serve as a unique probe of the neutrino electromagnetic moments with the advantage of not just separating the magnetic and electric moments but also identifying their individual elements. Both searching strategy and projected sensitivities are illustrated in this letter.
