论文摘要
Electroweak相变的动力学可能会对粒子物理和宇宙学产生深远的影响。我们研究了HL-LHC在I型I 2HDM中探测强型一阶电动相变（SFOEWPT）制度的前景。我们专注于Higgstrahung频道$ PP \ to ZH/A $，带有共鸣的顶级对最终状态$ h/a \ to t \ bar t $。我们发现，与Atlas和CMS已经执行的其他higgstrahlung搜索相比，Top-Quark对最终状态对SFOEWPT制度具有最大的敏感性，该搜索的重点是$ h/a \ to bb $ and bb $和$ h \ to ww $最终州。我们还得出了Higgstrahung搜索与HL-LHC上其他相关类别的搜索类别的互补性，并将它们与LISA的重力波灵敏度进行了比较。
The dynamics of electroweak phase transition could have profound consequences for particle physics and cosmology. We study the prospects for the HL-LHC to probe the strong first-order electroweak phase transition (SFOEWPT) regime in the type-I 2HDM. We focus on the Higgstrahlung channel $pp\to ZH/A$ with a resonant top-quark pair final state $H/A\to t\bar t$. We find that the top-quark pair final state renders the largest sensitivity to the SFOEWPT regime, in comparison to the other Higgstrahlung searches already performed by ATLAS and CMS, that focus on the $H/A\to bb$ and $H\to WW$ final states. We also derive the complementarity of the Higgstrahlung searches with other relevant classes of searches at the HL-LHC and compare them with the gravitational wave sensitivity at LISA.
