论文摘要
由于在螺旋状态的早期宇宙中脱钩，因此在天体物理磁场中传播的原始中微子在螺旋体磁场中传播并经历螺旋性变化。鉴于Xenon1t实验可能发现了太阳中微子的巨大磁矩，我们估计了宇宙和银河磁场中遗物中微子的螺旋性翻转。翻转概率对中微子磁矩和磁场的结构都是敏感的，因此可能是该场的探针。正如我们发现的那样，即使是远低于异种1T建议的磁矩，也可能会通过反tribβ衰变来显着影响遗物中微子的螺旋性及其检测率。
Since decoupling in the early universe in helicity states, primordial neutrinos propagating in astrophysical magnetic fields precess and undergo helicity changes. In view of the XENON1T experiment possibly finding a large magnetic moment of solar neutrinos, we estimate the helicity flipping for relic neutrinos in both cosmic and galactic magnetic fields. The flipping probability is sensitive both to the neutrino magnetic moment and the structure of the magnetic fields, thus potentially a probe of the fields. As we find, even a magnetic moment well below that suggested by XENON1T could significantly affect relic neutrino helicities and their detection rate via inverse tritium beta decay.
