| 英文摘要 | 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 Delta m(A/C) is an element of (-400, 400) GeV, tan beta is an element of (1, 50), and Delta m(A/C) is an element of (-200, 300) GeV, tan beta is an element of (1, 10) 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. |
