AI 中文摘要
冰立方二代（IceCube - Gen2）将实现精确测量高能宇宙中微子味比的梦想。受此前景推动，我们构建了一个中微子与暗物质相互作用的模型，并研究了活动星系核周围中微子与暗物质尖峰的相互作用对中微子味比测量的影响。我们表明，冰立方二代的味测量可以区分该模型与标准预期\((\nu_e^\oplus:\nu_\mu^\oplus:\nu_\tau^\oplus)\simeq (1/3:1/3:1/3)\)，以及对衰减μ子源的预测。我们讨论了如何通过将味比测量结果与确定中微子质量顺序的地面实验结果以及τ衰变模式测量中与标准模型预测的潜在偏差相结合，来获取有关尖峰以及构成它的暗物质粒子特性的信息。
英文摘要
IceCube-Gen2 is going to make the dream of precise flavor ratio measurement for high energy cosmic neutrinos a reality. Motivated by this prospect, we build a model for the interaction of neutrinos with the dark matter and study the impact of the neutrino interaction with the dark matter spike around active galactic nuclei on the neutrino flavor ratio measurement. We show that the flavor measurement by IceCube-Gen2 can discriminate between this model and the standard expectation, $(ν_e^\oplus:ν_μ^\oplus:ν_τ^\oplus)\simeq (1/3:1/3:1/3)$, as well as the prediction for a damped muon source. We discuss how we can derive information about the spike as well as about the characteristics of the dark matter particles composing it by combining the flavor ratio measurements with the results of the terrestrial experiments determining the neutrino mass ordering and a potential deviation from the standard model predictions in the measurements of the tau decay modes.
