论文摘要
中微子衰变以独特的方式修饰中微子的传播；中微子振荡中的风味不仅发生了变化，而且从初始中微子到最终中微子也有能量运输。目前，最敏感的直接探针是Icecube，它可以测量在乳层外距离上传播的中微子的能量和风味。我们首次计算可见和看不见的中微子衰变情况的风味过渡概率，包括宇宙膨胀的影响，并考虑对IceCube的影响。例如，我们演示了中微子decay如何解决IceCube数据中的张力。我们还提供了公开可用的代码来计算可见衰减的效果。
Neutrino decay modifies neutrino propagation in a unique way; not only is there flavor changing as there is in neutrino oscillations, there is also energy transport from initial to final neutrinos. The most sensitive direct probe of neutrino decay is currently IceCube which can measure the energy and flavor of neutrinos traveling over extragalactic distances. For the first time we calculate the flavor transition probability for the cases of visible and invisible neutrino decay, including the effects of the expansion of the universe, and consider the implications for IceCube. As an example, we demonstrate how neutrino decay addresses a tension in the IceCube data. We also provide a publicly available code to calculate the effect of visible decay.
