Descripción
We present the study of light charged Higgs boson (H−) production and neutral Higgs bosons at future electron-proton colliders; both in the Large Hadron electron Collider (LHeC) and Future Circular Collider in the mode hadron-electron (FCC-he). We study the charged current production processes: 𝑒−𝑝→𝜈_𝑒 𝑞𝐻^− and 𝑒−𝑝→𝜈_𝑒 𝑞 𝜙 (𝜙=ℎ,𝐻), considering for the charged Higgs the decay channels 𝐻→𝑏𝑐 ̅ and 𝐻→𝜏𝜈 ̅_𝜏 and for the neutral Higgs bosons with the flavor violating decays of the Higgs bosons, as well as
𝐻→𝑐𝑐 ̅ . We analyze the processes in the framework of the 2-Higgs Doublet Model Type-III (2HDM-III), assuming a four-zero texture in the Yukawa matrices and a general Higgs potential. We consider a variety of both reducible and irreducible backgrounds for the signals of the 𝐻− state and 𝜙-states. We show that the detection of a light charged Higgs boson or neutral Higgs bosons are feasible in the aforementioned final states, assuming for the LHeC and FCC-he the standard energy and luminosity conditions stablished to theses colliders.
