Description
The Large Hadron-electron Collider (LHeC) is a proposed upgrade of the LHC at CERN. It consists of an ERL providing electrons to collide with the HL-LHC, HE-LHC and the FCC-hh proton beams achieving centre-of-mass energies 1.3-3.5 TeV and luminosities $\sim 10^{34}$ cm$^{−2}$ s$^{-1}$, respectively. These large energies and luminosities lead to charged current Higgs production cross sections which are comparable (LHeC) or 3-4 times larger (FCC-eh) than those of $Z$-Higgs-strahlung at $e^+e^-$ colliders. In this talk we present the latest results on the determination of Higgs couplings, both in $ep$ at the LHeC and the FCC-eh, and in combination with their hadronic counterparts HL-LHC/HE-LHC and FCC-hh, exhibiting a strong $ep+pp$ synergy and very interesting complementarity to $e^+e^-$ Higgs prospects. We also show the implication that a precise determination of PDFs in $ep$ has for precision Higgs measurements at hadron colliders.
