论文摘要
在两个Higgs Doublet模型的背景下，我们探索了弱规模右中微子的暗物质现象学。直接检测实验中的预期信号与通常的自旋依赖性和自旋依赖性分类不同，因为带有夸克的散射取决于暗物质自旋。暗物质遗物密度是通过热冻结和非标准宇宙学设置的，在非标准宇宙学的情况下，Abelian仪表对称是暗物质生产机制的关键。我们表明，这种对称性使我们能够同时解决中微子质量，并在两个Higgs Doublet模型构造中存在的风味问题。最后，我们概述了遵守对撞机的参数空间区域，扰动单位性和直接检测约束。
We explore the dark matter phenomenology of a weak-scale right-handed neutrino in the context of a Two Higgs Doublet Model. The expected signal at direct detection experiments is different from the usual spin-independent and spin-dependent classification since the scattering with quarks depends on the dark matter spin. The dark matter relic density is set by thermal freeze-out and in the presence of non-standard cosmology, where an Abelian gauge symmetry is key for the dark matter production mechanism. We show that such symmetry allows us to simultaneously address neutrino masses and the flavor problem present in general Two Higgs Doublet Model constructions. Lastly, we outline the region of parameter space that obeys collider, perturbative unitarity and direct detection constraints.
