论文摘要
除了解决小层次结构问题的解决方案外，《镜子双Higgs》还为不对称的暗物质提供了自然的环境。但是，在只有一个希格斯双重副本及其镜像副本的化身中，暗物质几乎可以肯定主要由镜像原子组成，这被对暗物质自我互动的限制严重排除。通过添加第二个Higgs Doublet及其镜子，可以安排不同的希格斯人的VEV，以使暗物质主要由镜面中子组成，这在宇宙学上可行。在本文中，结果表明，当前的限制因素，风味和宇宙学可以容纳这种VEV结构，而必要的调整几乎没有增加。
In addition to being a solution to the little hierarchy problem, the Mirror Twin Higgs provides a natural setting for Asymmetric Dark Matter. In its incarnation with only one Higgs doublet and its mirror copy, dark matter would however almost certainly consist mostly of mirror atoms, which is severely ruled out by constraints on dark matter self-interactions. By adding a second Higgs doublet and its mirror, the vevs of the different Higgses can be arranged such that dark matter consists mostly of mirror neutrons, which is cosmologically viable. In this paper, it is shown that current constraints from colliders, flavour and cosmology can accommodate such a vev structure with little increase in the necessary tuning.
