Description

Higgs production cross sections at LHeC (FCC-eh) energies are as large as (larger than) those at future $Z-H$ $e^+e^-$ colliders. This provides alternative and complementary ways to obtain very precise measurements of the Higgs couplings, primarily from luminous, charged current DIS. Recent results for LHeC and FCC-eh, as contained in the 2020 LHeC White paper, are shown and their combination with pp (HL-LHC) cross sections is presented leading to precision comparable for some couplings to the most promising $e^+e^-$ colliders. We will show the results for the determination of several signal strengths and couplings to quarks, leptons and EW bosons, and discuss the possibilities for measuring the coupling to top quarks and its CP phase, and the search for invisible decays.
