论文摘要
我们研究了构成额外的惰性希格斯双线和三组右撇子中微子的最低术模型。 Scotogenic模型连接暗物质，宇宙的重子不对称和中微子振荡数据。在我们的工作中，我们通过TEV量表的衰减重质量中性单重手指（$ n_ {2} $）获得了男性生成。我们主要关注$ m_w <m_ {dm} \ le550 $ gev之内的暗物质中间质量区域，由于共同灭绝过程，观察到的遗物密度被抑制了。我们考虑了暗物质生产的热和非热方法，并探讨了最轻的稳定候选者是暗物质候选者的可能性。在Higgs Doublet（IHD）沙漠中，我们探索了一个新的允许的暗物质质量区域，用于非热生成暗物质，并在惰性标量中质量分配10 GEV。我们还看到遗物丰度在标量之间质量分裂不等的变化。在本研究中，还验证了在活性中微子的有效质量上结合的Kamland-Zen。
We study the minimal scotogenic model constituting an additional inert Higgs doublet and three sets of right-handed neutrinos. The scotogenic model connects dark matter, baryon asymmetry of the Universe and neutrino oscillation data. In our work, we obtain baryogenesis by the decay of TeV scale heavy neutral singlet fermion ($N_{2}$). We primarily focus on the intermediate-mass region of dark matter within $M_W<M_{DM}\le550$ GeV, where observed relic density is suppressed due to co-annihilation processes. We consider thermal as well as the non-thermal approach of dark matter production and explore the possibility of the lightest stable candidate being a dark matter candidate. Within the inert Higgs doublet (IHD) desert, we explore a new allowed region of dark matter masses for the non-thermal generation of dark matter with a mass splitting of 10 GeV among the inert scalars. We also see the variation of relic abundance for unequal mass splitting among the scalars. The KamLand-Zen bound on the effective mass of the active neutrinos is also verified in this study.
