论文摘要
在这项工作中,我们研究了风味异常刺激的新物理学的影响,通过密集的暗物质光环对中微子振荡。受到模型的启发,在该模型中,我们在一个环水平上促成了$ b \ to $ b \ tosμ^+μ^ - $过渡,我们研究了中微子 - 漆黑物质互动对超高能量宇宙中性中微子的超高能量中微子的振荡模式的影响,该模式穿过这个Muonphilic Halo附近的Milo MiLKY Way Center MiLky。我们发现,由于这种相互作用,到达地球的中微子的风味比与真空振荡不同。我们还将$ z'$模型视为由$l_μ-l_τ$对称驱动的,并包含矢量般的费米昂作为暗物质候选者。以前证明,对于这样的模型,中微子的三种口味彼此脱离。这将使风味比与真空振荡相似。因此,中微子与密集的暗物质光环的相互作用可以作为区分具有深色连接风味模型的重要工具。
In this work we study the impact of new physics, stimulated by flavor anomalies, on neutrino oscillations through dense dark matter halo. Inspired by a model where a Majorana dark matter fermion and two new scalar fields contribute to $b \to s μ^+ μ^-$ transition at the one loop level, we study the impact of neutrino-dark matter interaction on the oscillation patterns of ultra-high energy cosmic neutrinos passing through this muonphilic halo located near the center of Milky Way. We find that due to this interaction, the flavor ratios of neutrinos reaching earth would be different from that of vacuum oscillations. We also consider a $Z'$ model driven by $L_μ-L_τ$ symmetry and containing a vector-like fermion as a dark matter candidate. It was previously shown that for such a model, the three flavors of neutrinos decouple from each other. This will render a flavor ratio similar to that of vacuum oscillations. Therefore, the interaction of neutrinos with dense dark matter halo can serve as an important tool to discriminate between flavor models with a dark connection.
