Description
In light of the recent deviation in the W boson mass measurement from the CDF-II, which significantly strays from the Standard Model (SM) prediction, our paper explores the implications of this within the framework of the Two-Higgs Doublet Model (2HDM). We focus on the scenario where the heavy CP-even H is recognized as the Higgs boson observed at 125 GeV.
Our analysis, which incorporates both theoretical and current experimental constraints along with the new CDF measurement, suggests that the 2HDM parameter space can offer a substantial adjustment. This adjustment aligns the predicted W mass more closely with the new CDF $M_W$ measurement.
Our study also reveals that the equality $M_{H^\pm} = M_A$ is not supported, and there is a positive splitting between the charged Higgs boson and all other states. Additionally, we delve into the influence on the effective mixing angle $\sin^2 θ_eff$ and the potential effects on the decays of the charged Higgs and CP-odd Higgs boson in the context of 2HDM type-I and type-X.
