论文摘要
我们在受辐射型II Seessaw和Scotogenic场景启发的模型中探讨了暗物质与中微子之间的联系。在我们的模型中，我们介绍了新的电荷态（标量和类似矢量的费米昂），并施加了离散的$ \ mathbb {z} _2 $对称。中微子质量是在循环级别生成的，最轻的$ \ mathbb {z} _2 $ -ODD中性粒子是稳定的，它可以扮演暗物质候选者的角色。我们对模型进行数值分析，表明除正确的暗物质密度外，还可以再现中微子质量和风味结构，而可行的DM质量从700 GEV到30 TEV。我们探索直接和间接的检测特征，并显示CTA，Darwin和KM3NET的有趣检测前景，并突出了这些可观察到的物品之间的互补性。
We explore the connection between Dark Matter and neutrinos in a model inspired by radiative Type-II seessaw and scotogenic scenarios. In our model, we introduce new electroweakly charged states (scalars and a vector-like fermion) and impose a discrete $\mathbb{Z}_2$ symmetry. Neutrino masses are generated at the loop level and the lightest $\mathbb{Z}_2$-odd neutral particle is stable and it can play the role of a Dark Matter candidate. We perform a numerical analysis of the model showing that neutrino masses and flavour structure can be reproduced in addition to the correct dark matter density, with viable DM masses from 700 GeV to 30 TeV. We explore direct and indirect detection signatures and show interesting detection prospects by CTA, Darwin and KM3Net and highlight the complementarity between these observables.
