Many of the new physics models predict a light Higgs boson similar to the Higgs boson of the Standard Model (SM) and also extra scalar bosons. Beyond the search channels for a SM Higgs boson, the future collider experiments will explore additional channels that are specific to extended Higgs sectors. We study the charged Higgs boson production within the framework of two Higgs doublet models (THDM) in the proton-proton collisions at a future circular hadron collider (FCC- hh). With an integrated luminosity of Lint = 500 fb−1 at very high energy frontier (√s = 100 TeV), we obtain a significant coverage of the parameter space and distinguish the charged Higgs- top-bottom interaction within the THDM or other new physics models with charged Higgs boson mass up to 1.5 TeV.
