论文摘要
我们分析了相干中微子核散射的相干实验的新数据，以研究中微子的电磁相互作用。现在的统计和精度几乎是两倍，观察到的过程的统计显着性现已提高到11.6 $σ$。我们使用新的相干数据对中微子的电磁特性产生了限制。与先前的界限相比，约束提高了两个以上。此外，我们讨论了较低能量后中微子毫米的独特行为，并显示了其对标准模型贡献的干扰，后坐力能量的逆强力以及与其他相互作用相比的质量。
We analyze new data from the COHERENT experiment of the coherent neutrino-nucleus scattering to investigate the electromagnetic interactions of neutrinos. With almost double the statistics and precision now, the statistical significance of the observed process has now enhanced to 11.6$σ$. We derive constraints on the electromagnetic properties of neutrinos using the new COHERENT data. The constraints improve by more than a factor of two compared to the previous bounds. Furthermore, we discuss the unique behavior of the neutrino millicharge at lower energy recoils and show its unique dependence on its interference with the standard model contribution, inverse power of recoil energy and the mass of the target particle in comparison to the other interactions.
