论文摘要
我们在一个共同的框架中考虑了暗物质和瘦物质发生之间的相互作用，其中三个右撇子中微子，一个费米子暗物质和两个单型标量被引入标准模型中。两个单重标量标量的混合不仅决定了暗物质遗物密度，而且还将右手中微子与暗物质联系起来。我们认为，重子不对称是通过谐振诱饵发生产生的，右手中微子肿块在TEV水平上。我们提供一个满足遗物密度约束的可行参数空间，并且在较大的混合角度的情况下，参数空间更加灵活。我们发现，模型中的暗物质的存在不仅可以稀释巴属不对称性，而且还可以由于暗物质ni灭过程成一对右手中微子而产生较大的巴属不对称性，尽管即使暗物质质量比右手中微子质量较轻，但即使暗物质质量更轻。增强效果取决于暗物质质量$m_χ$以及右手中微子质量$ m_n $，并且在$ M_N = 800 $ GEV的情况下，仍然可以找到增强的BARYON不对称性。
We consider the interplay between dark matter and leptogenesis in a common framework, where three right-handed neutrinos, one fermionic dark matter and two singlet scalars are introduced into the Standard Model. The mixing of the two singlet scalars not only determine the dark matter relic density but also connect right-handed neutrino with dark matter. We consider that the baryon asymmetry is generated via the resonant leptogenesis and the right-handed neutrino masses are at TeV level. We present a viable parameter space satisfying relic density constraint, and the parameter space is more flexible in the case of a larger mixing angle. We found that the existence of dark matter in the model can not only dilute the baryon asymmetry but can also generate a larger baryon asymmetry due to the process of dark matter annihilation into a pair of right-handed neutrinos even though dark matter mass is lighter than right-handed neutrino mass. The enhanced effect depends on the dark matter mass $m_χ$ as well as right-handed neutrino mass $m_N$, and one still can find a baryon asymmetry enhanced in the case of $m_N=800$ GeV.
