Exploring CP-even scalars of a Two Higgs-doublet model in future $e^{-}p$ colliders

Abstract

In this proceeding we shall explore the potential of a future $e^{-}p$ collider to probe the CP-even scalars in a two Higgs doublet model. We consider Type-I in this study. The mass of the lighter scalar particle is considered to be the Higgs-boson, $m_h=125$ GeV, and a heavy scalar $m_H=270$ GeV. The centre of mass energy for the $e^{-}p$ collision is considered as in the Large Hadron Electron Collider and the Future Circular Hadron Electron Collider configurations, by fixing the proton beam energy to be $E_p=7$ and 50 TeV, respectively, and an electron beam energy of $E_e=60$ GeV. Production cross sections of these scalars are also shown at higher electron beam energies. Future prospects of these studies are also discussed.
