在活跃中微子和惰性中微子之间存在跃迁磁矩的情况下，在相干弹性中微子-核散射（）实验中寻找Primakoff上散射过程可以对中微子磁矩提供严格的约束。我们表明，辐射上散射过程与发射的光子在最终状态可以诱导一个新的符合信号ateximents，也可以探测中微子跃迁磁矩超出现有的限制。此外，这种辐射模式的微分分布也可能对介导该过程的无菌状态的狄拉克与马约拉纳性质敏感。这对研究轻活动中微子的性质和质量产生机制具有重要意义。
In the presence of transition magnetic moments between active and sterile neutrinos, the search for a Primakoff upscattering process at coherent elastic neutrino-nucleus scattering () experiments can provide stringent constraints on the neutrino magnetic moment. We show that a radiative upscattering process with an emitted photon in the final state can induce a novel coincidence signal atexperiments that can also probe neutrino transition magnetic moments beyond existing limits. Furthermore, the differential distributions for such a radiative mode can also potentially be sensitive to the Dirac vs Majorana nature of the sterile state mediating the process. This can provide valuable insights into the nature and mass generation mechanism of the light active neutrinos.
