论文摘要
我们通过深色 - 物质的回荡研究了冻结重生发生的宇宙学和现象学,将暗物质带到了标准模型的瘦素上。我们调查了有或没有$ Z_2 $对称性的可行模型,根据这些模型,所有新字段均已收取。在这些模型中,Lepton的风味效应对于瘦生成很重要,我们确定了Baryon不对称性在参数上与无菌中微子振荡的参数差异和增强的场景。我们研究的模型预测了新的,电动电荷的场的存在,可以通过对撞机搜索,结构形成研究,X射线观测和陆地低能测试的结合来测试。
We study the cosmology and phenomenology of freeze-in baryogenesis via dark-matter oscillations, taking the dark matter to couple to Standard Model leptons. We investigate viable models both with and without a $Z_2$ symmetry under which all new fields are charged. Lepton flavor effects are important for leptogenesis in these models, and we identify scenarios in which the baryon asymmetry is parametrically distinct from and enhanced relative to leptogenesis from sterile neutrino oscillations. The models we study predict the existence of new, electroweak-charged fields, and can be tested by a combination of collider searches, structure-formation studies, X-ray observations, and terrestrial low-energy tests.
