论文摘要
在这项工作中，我们重新审查了强大的一阶electroweak相变（SFOEWPT）和最近的$ M_W $ PRECISION测量在I型和II类型2HDM中。 SFOEWPT对2HDM中的O（100）GEV新标量偏爱，这对于电动eakeak baryogeneseis是必不可少，并且也观察到$ m_w $ shift。 ％我们发现，在当前约束下，I型和II类型2HDM都可以解释SFOEWPT，Z-POLE，HIGGS精度测量以及$ M_W $同时对CDF-II的精确测量，并且所有这些精度测量对2HDM的重型HIGGS质量分解都敏感。 The allowed regions are $Δm_{A/C} \in (-400, 400) GeV, \tanb\in(1,50)$, and $Δm_{A/C} \in (-200, 300) GeV, \tanb\in(1,12)$ for Type-I and Type-II 2HDM respectively.此外，对Higgs和$ Z $ Boson Properties的Future Lepton Collider测量可以更详细地探索此情况，甚至排除在外。
In this work we revisit the existence of a strong first order electroweak phase transition (SFOEWPT) and recent $m_W$ precision measurement in the Type-I and Type-II 2HDMs. The O(100) GeV new scalars in 2HDMs are favored by SFOEWPT, which is necessary for electroweak baryogenesis, and observed $m_W$ shift as well. % We find that under current constraints, both Type-I and Type-II 2HDM can explain the SFOEWPT, Z-pole, Higgs precision measurements and $m_W$ precision measurement of CDF-II at same time, and all these precision measurements are sensitive to heavy Higgs mass splitting in 2HDM. The allowed regions are $Δm_{A/C} \in (-400, 400) GeV, \tanb\in(1,50)$, and $Δm_{A/C} \in (-200, 300) GeV, \tanb\in(1,12)$ for Type-I and Type-II 2HDM respectively. Furthermore future lepton collider measurements on Higgs and $Z$ boson properties can explore this scenario in more detail or even rule out it.
