Description
tudying the properties of Standard Model (SM) – like Higgs boson becomes one important window to explore the physics beyond the SM. In our works, we present studies about the implications of the Higgs and Z-pole precision measurements at current LHC and future Higgs Factories. We perform a global fit to various Higgs search channels to obtain the 95% C.L. constraints on the model parameter spaces of Two Higgs Double Model (2HDM). In the 2HDM, we analyse tree level effects as well as one-loop contributions from the heavy Higgs bosons. The strong constraints on cos(β − α), mΦ and heavy Higgs mass splitting can be complementary to direct search of the LHC and Z pole precision measurements. Our works also scrutinize the relationship between SFOPT required by baryogenesis and SM-Higgs coupling deviation at LHC and future lepton colliders.
