论文摘要
我们研究了最近提出的具有CP违规的男性生成模型的Electroweak相变模式，起源于黑暗扇区。该型号包括一个复杂的标量单元式玻色子门户网站，A $ u（1）_l $ gauge Lepton对称性具有$ z^\ prime $ $级玻色子门户和费米子的暗物质粒子。我们发现了标量领域的新型热历史，它具有$ Z_2 $打破单线真空吸尘器，这是由黑暗Yukawa耦合驱动的早期宇宙中的，可引起一步强烈的一阶electroweak相位过渡。我们探讨了产生观察到的物质抗对称和暗物质遗物丰度的参数空间，同时与电动偶极矩和撞机搜索的约束以及暗物质直接检测范围保持一致。可以通过Higgs门户产生复杂的单元，并在一定距离行驶后腐烂到标准模型颗粒中。我们在{\ ution [13] {tev}}的长寿命单元量标量的范围内，带有$ \ mathcal {l} = \ ution [139] {fb^{ - 1}} $，并显示其对模型参数空间的影响。撇开目前尚未解决的理论不确定性，我们估计未来观测值可检测到的引力波特征。
We investigate the electroweak phase transition patterns for a recently proposed baryogenesis model with CP violation originated in the dark sector. The model includes a complex scalar singlet-Higgs boson portal, a $U(1)_l$ gauge lepton symmetry with a $Z^\prime$ gauge boson portal and a fermionic dark matter particle. We find a novel thermal history of the scalar sector, featuring a $Z_2$ breaking singlet vacuum in the early Universe driven by a dark Yukawa coupling, that induces a one-step strongly first order electroweak phase transition. We explore the parameter space that generates the observed matter-antimatter asymmetry and dark matter relic abundance, while being consistent with constraints from electric dipole moment and collider searches, and dark matter direct detection bounds. The complex singlet can be produced via the Higgs portal and decays into Standard Model particles after traveling a certain distance. We explore the reach for long-lived singlet scalars at the {\unit[13]{TeV}} Large Hadron Collider with $\mathcal{L}=\unit[139]{fb^{-1}}$ and show its impact on the parameter space of the model. Setting aside currently unresolved theoretical uncertainties, we estimate the gravitational wave signatures detectable at future observatories.
