Is the new CDF $M_W$ measurement consistent with the two higgs doublet model?
Abstract
Motivated by the new CDF measurement of the boson mass reported recently which clearly illustrates a large deviation compared to the Standard Model (SM) prediction. In the present paper, we study the Two-Higgs Doublet Model (2HDM) contributions to and its phenomenological implications in the case where the heavy CP-even is identified as the observed Higgs boson with a mass of GeV. Taking into account theoretical and all the available experimental constraints as well as the new CDF measurement, we demonstrate that the 2HDM parameter space can provide a large correction which predicts the W mass close to the new CDF measurement. It is found that is excluded and the splitting of the charged Higgs boson with all other states is positive. We also discuss the consequence on the effective mixing angle as well as the phenomenological implications on the charged Higgs and CP-odd decays.
