Probing Anomalous HZZ Couplings at the LHeC

Abstract

We examine the sensitivity to the couplings of the Higgs boson to neutral gauge bosons in a model independent way at the Large Hadron electron Collider (LHeC). We have obtained the constraints on anomalous couplings for $HZZ$ vertex via the process $e^{-}p\to e^{-}HqX$. We find the accessible limits of the anomalous coupling $b_Z$ as $(-0.12,0.43)$ and $(-0.10,0.33)$, while the limits on coupling ${\beta }_Z$ as ($-0.32,0.32$) and $(-0.24,0.24)$ at the electron beam energy $E_e=60$ GeV and $E_e=140$ GeV, respectively.
