Probing the hcc¯ coupling at a Future Circular Collider in the electron-hadron mode
We study the production of a neutral Higgs boson at a Future Circular Collider in the electron-hadron mode (FCC-eh) through the leading process e - p → ν e h q assuming the decay channel h → c c ¯ , where h is the Standard Model (SM)-like state discovered at the Large Hadron Collider (LHC).
