论文摘要
在本文中，我们研究了$l_μ-l_τ$模型中狄拉克暗物质的现象学，并研究了黑晕中中微子振荡。由于暗物质与Muon Neutminino和Tau Neutrino具有相反的符号耦合，因此它为中微子风味过渡幅度的演化方程贡献了有效的潜力，$ \ pma_χ$，这对于在密集的暗物质环境中的高能中微子振荡可能很重要。我们使用完整的数值计算讨论了中微子质量，Lepton混合角，Dirac CP相和中微子振荡概率。结果表明，中微子可以忍受非常不同的物质影响。当潜在的$a_χ$变为超大时，三种中微子的口味会彼此脱熟料。
In this paper, we study the phenomenology of a Dirac dark matter in the $L_μ-L_τ$ model and investigate the neutrino oscillation in the dark halo. Since dark matter couples to the muon neutrino and the tau neutrino with opposite sign couplings, it contributes effective potentials, $\pm A_χ$, to the evolution equation of the neutrino flavor transition amplitude, which can be significant for high energy neutrino oscillations in a dense dark matter environment. We discuss neutrino masses, lepton mixing angles, Dirac CP phase, and neutrino oscillation probabilities in the dark halo using full numerical calculations. Results show that neutrinos can endure very different matter effects. When the potential $A_χ$ becomes ultra-large, three neutrino flavors decouple from each other.
