Description
The measurement of the quartic coupling between a Higgs boson pair and a vector boson pair is expected to be achieved from vector-boson fusion (VBF) production of a Higgs boson pair at the LHC. However, this process involves another unmeasured parameter, the trilinear Higgs self-coupling. Since the LHC cannot avoid the gluon fusion pollution, which becomes severe for anomalous Higgs trilinear coupling, an electron-proton collider is more appropriate for the comprehensive measurement. In this regard, we study the VBF production of a Higgs boson pair in the bbbb final state at the LHeC and FCC-he. Performing detailed analysis using the simulated dataset, we devise the search strategy specialized at the LHeC and FCC-he and give a prediction for the sensitivity to both couplings. We find that the two electron-proton colliders have high potential.
