中微子有相当大的自相互作用吗？他们可能会。实验室的限制很弱，因此在天体物理环境和早期宇宙中可能会产生强烈的影响。使用中微子望远镜进行观测可以提供中微子自（“秘密”）相互作用的独立探测，因为中微子源很远并且宇宙中微子背景介入。我们制定了一个路线图，以便在测试由光介体控制的秘密中微子相互作用方面取得决定性进展。这一进展将通过 IceCube-Gen2 对高能天体物理中微子的观测来实现。对此至关重要的是我们对理论的综合处理，考虑到以前被忽视或过于近似的效应，以及包括现实的检测物理学。我们表明，IceCube-Gen2 可以充分发挥中微子天文学测试中微子自相互作用的潜力，并对宇宙学相关的相互作用模型敏感。为了促进即将进行的研究，我们发布了 nuSIProp，该代码也可用于研究各种来源的中微子自相互作用。
Do neutrinos have sizable self-interactions? They might. Laboratory constraints are weak, so strong effects are possible in astrophysical environments and the early universe. Observations with neutrino telescopes can provide an independent probe of neutrino self ("secret") interactions, as the sources are distant and the cosmic neutrino background intervenes. We define a roadmap for making decisive progress on testing secret neutrino interactions governed by a light mediator. This progress will be enabled by IceCube-Gen2 observations of high-energy astrophysical neutrinos. Critical to this is our comprehensive treatment of the theory, taking into account previously neglected or overly approximated effects, as well as including realistic detection physics. We show that IceCube-Gen2 can realize the full potential of neutrino astronomy for testing neutrino self-interactions, being sensitive to cosmologically relevant interaction models. To facilitate forthcoming studies, we release nuSIProp, a code that can also be used to study neutrino self-interactions from a variety of sources.
