Marcela Carena, Claudius Krause, Zhen Liu, Yikun Wang

摘要:

电弱对称性的不恢复到高温远高于电弱标度提供了新的选择重子。我们提出了一种新的方法,通过惰性希格斯部门耦合到标准模型希格斯以及扩展的标量单重态部门的电弱对称性非恢复。我们实施重整化群的改进和热重定,必要的评估跨越广泛的能量尺度和温度的有效潜力。我们提出的基准方案的例子,允许电弱对称性非恢复所有的方式高达数百TeV的温度,还具有抑制sphaleron冲洗因子下降到电弱规模。我们的方法传输的标准模型破缺的电弱对称性的惰性希格斯部门有几个有趣的影响(电弱)重子生成,早期宇宙的热历史,并可以通过希格斯物理现象学和电弱精密测量在HL-LHC仔细检查。

英文摘要:

Electroweak symmetry non-restoration up to high temperatures well above the electroweak scale offers new alternatives for baryogenesis. We propose a new approach for electroweak symmetry non-restoration via an inert Higgs sector that couples to the Standard Model Higgs as well as an extended scalar singlet sector. We implement renormalization group improvements and thermal resummation, necessary to evaluate the effective potential spanning over a broad range of energy scales and temperatures. We present examples of benchmark scenarios that allow for electroweak symmetry non-restoration all the way up to hundreds of TeV temperatures, and also feature suppressed sphaleron washout factors down to the electroweak scale. Our method for transmitting the Standard Model broken electroweak symmetry to an inert Higgs sector has several intriguing implications for (electroweak) baryogenesis, early universe thermal histories, and can be scrutinized through Higgs physics phenomenology and electroweak precision measurements at the HL-LHC.
