论文摘要

我们讨论了两个对齐的Higgs Doublet模型中的Electroweak男性生成。众所周知,在该模型中,可以通过HIGGS部门的CP侵略效应之间的破坏性干扰来避免电子偶极矩的实验结果严重限制。在我们以前的工作中,我们表明可以解释宇宙中观察到的重子数,而不会在同一模型中特定方案中与当前可用数据相矛盾。我们在这里首先根据WKB方法讨论对BARYON数字的评估细节,并考虑到墙壁速度的所有顺序。然后,我们研究了参数空间,这些空间在对撞机,风味和电动偶极矩实验的当前可用数据下允许。我们发现几个基准场景可以解释宇宙的重子不对称。我们还讨论了如何在未来的对撞机实验,各种风味实验和引力波观测的情况下测试这些基准测试场景。

We discuss electroweak baryogenesis in aligned two Higgs doublet models. It is known that in this model the severe constraint from the experimental results for the electron electric dipole moment can be avoided by destructive interference among CP-violating effects in the Higgs sector. In our previous work, we showed that the observed baryon number in the Universe can be explained without contradicting current available data in a specific scenario in the same model. We here first discuss details of the evaluation of baryon number based on the WKB method taking into account all order of the wall velocity. We then investigate parameter spaces which are allowed under the current available data from collider, flavor and electric dipole moment experiments simultaneously. We find several benchmark scenarios which can explain baryon asymmetry of the Universe. We also discuss how we can test these benchmark scenarios at future collider experiments, various flavor experiments and gravitational wave observations.
