论文摘要
在文献中研究了主动中微子的自我交流，以减轻$ H_0 $张力。类似的自我交流还可以解释来自Icecube探测器中遥远的星体物理源的中微子的磁通中观察到的倾角。与考虑解决$ H_0 $张力的风味通用中微子相互作用相反，该张力是从粒子物理实验中排除的，我们考虑了风味特定的中微子相互作用。我们表明，解释IceCube DIPS所需的自我相互作用耦合常数和中介质量的值与BAO，HST和PLANCK数据的组合所偏爱的强中微子自我相互作用不一致。但是，用于解释IceCube倾角的倒置层次结构中的tau中微子（$ν_τ$）之间所需的自我相互作用与宇宙学界限的中等自我交互区域一致。对于其他相互作用和层次结构，ICECUBE首选的自我相互作用与仅在2- $σ$级别的宇宙学界限的中等自我交互区域一致。
Self-interaction in the active neutrinos is studied in the literature to alleviate the $H_0$ tension. Similar self-interaction can also explain the observed dips in the flux of the neutrinos coming from the distant astro-physical sources in IceCube detectors. In contrast to the flavour universal neutrino interaction considered for solving the $H_0$ tension, which is ruled out from particle physics experiments, we consider flavour specific neutrino interactions. We show that the values of self-interaction coupling constant and mediator mass required for explaining the IceCube dips are inconsistent with the strong neutrino self-interactions preferred by the combination of BAO, HST and Planck data. However, the required amount of self-interaction between tau neutrinos ($ν_τ$) in inverted hierarchy for explaining IceCube dips is consistent with the moderate self-interaction region of cosmological bounds at 1-$σ$ level. For the case of other interactions and hierarchies, the IceCube preferred amount of self-interaction is consistent with moderate self-interaction region of cosmological bounds at 2-$σ$ level only.
