The possible effect on the flavour spectra of astronomical neutrinos from a neutrino-dark matter interaction has been investigated for decoherent neutrinos. In this work, we report results calculated for coherent neutrinos. This was done with two different models for the neutrino dark-matter interactions: a flavour state interaction,as for the weak interaction in the Standard Model, and a mass state interaction, which is predicted by certain non-Standard Models (specifically Scotogenic models). It was found that using a coherent analysis dramatically increased the explorable parameter space for the neutrino-dark matter interaction. However, the detection of coherent astronomical neutrinos presents a significant challenge to experimentalists, because such a detection would require an improvement in energy resolution by at least six orders of magnitude, with similar improvements in astronomical distance determinations.

有意义的细节：为中微子-暗物质效应增加基线依赖性的价值

已经针对退相干中微子研究了中微子-暗物质相互作用对天文中微子风味光谱的可能影响。在这项工作中，我们报告了相干中微子的计算结果。这是通过两种不同的中微子暗物质相互作用模型完成的：味道状态相互作用，如标准模型中的弱相互作用，以及质量状态相互作用，由某些非标准模型（特别是 Scotogenic 模型）预测. 发现使用相干分析显着增加了中微子-暗物质相互作用的可探索参数空间。然而，相干天文中微子的探测对实验者来说是一个重大挑战，
