论文摘要
我们使用太阳中微子 - 电子弹性散射的最新Xenonnt数据来获得中微子电磁相互作用以及弱耦合光载体和标量介体的新限制。 Xenonnt已经报道了世界上对无关的有效中微子磁矩的最佳限制，几乎是暴露和系统的两倍。我们扩展了此分析，并对所有可能的电磁相互作用以及风味的通用光仪玻色子耦合和质量产生限制，这可能有助于中微子电子弹性散射过程。我们考虑了中微子磁矩，毫米，电荷半径和反磁相互作用的中微子磁矩，电荷半径和Anapole矩与风味无关和风味依赖性的相互作用。磁矩，millicharge，向量和标量相互作用的新限制通过大约一个数量级提高。同时，在中微子电荷半径和Anapole矩时，相对较弱的改善。
We derive new limits on the neutrino electromagnetic interactions and weakly coupled light vector and scalar mediators using the recent XENONnT data of the solar neutrino-electron elastic scattering. XENONnT has already reported the world's best constraint on the flavor-independent effective neutrino magnetic moment with almost twice the exposure and improved systematics. We extend this analysis and derive constraints on all the possible electromagnetic interactions and flavor universal light gauge boson couplings and masses, which could contribute to the neutrino-electron elastic scattering process. We consider both flavor-independent and flavor-dependent interactions of the neutrino magnetic moments, millicharges, charge radii, and anapole moments for the electromagnetic interactions. The new limits on the magnetic moment, millicharge, vector, and scalar interactions are improved by about one order of magnitude. At the same time, there is relatively weaker improvement in the case of neutrino charge radii and anapole moments.
