摘要： 在重子生成和暗物质的标准模型中，两个领域中的密度生成机制是彼此无关的。 在本文中，我们探讨了通过暗物质领域产生重子不对称性的模型，同时将重子不对称性与暗物质密度联系起来。 在我们探讨的模型类别中，通过一阶相变在隐藏领域中产生了暗物质不对称性。 在隐藏领域中，很容易实现足够强的一阶相变以及足够大的$CP $破坏，以产生观测到的不对称性。 这可能发生在电弱相变之上或之下，但在两种情况下都显著早于暗物质变得非相对论性。 我们研究了对称暗物质密度随后通过微扰和非微扰通信机制传递给重子的例子，并表明在两种情况下宇宙学约束都被满足，同时可以产生足够的重子不对称性。 显示英文摘要

摘要： In standard models of baryogenesis and of dark matter, the mechanisms which generate the densities in both sectors are unrelated to each other. In this paper we explore models which generate the baryon asymmetry through the dark matter sector, simultaneously relating the baryon asymmetry to the dark matter density. In the class of models we explore, a dark matter asymmetry is generated in the hidden sector through a first order phase transition. Within the hidden sector, it is easy to achieve a sufficiently strong first order phase transition and large enough $CP $ violation to generate the observed asymmetry. This can happen above or below the electroweak phase transition, but in both cases significantly before the dark matter becomes non-relativistic. We study examples where the Asymmetric Dark Matter density is then transferred to the baryons both through perturbative and non-perturbative communication mechanisms, and show that in both cases cosmological constraints are satisfied while a sufficient baryon asymmetry can be generated.
