Abstract

The future Large Hadron electron Collider (LHeC) would allow collisions of an intense electron beam with protons or heavy ions at the High Luminosity-Large Hadron Collider (HL-LHC). Owing to a center of mass energy greater than a TeV and very high luminosity ( $\sim$ $\sim$ 1 $a b^{- 1}$ $ab^{-1}$ ), the LHeC would not only be a new generation collider for deep-inelastic scattering (DIS) but also an important facility for precision Higgs physics, complementary to pp and $e^{+} e^{-}$ $$e^+e^-$$ colliders. Previously, it has been found that uncertainties of $0.8 %$ $0.8\%$ and $7.4 %$ $7.4\%$ can be achieved on the Higgs boson coupling strength to b- and c-quarks respectively. These results were obtained in the fast simulation frameworks for the LHeC detector. Focusing on the dominant Higgs boson decay channel, $H \to b b$ $H\rightarrow bb$ , the present work aims to give a comparison of these results with a fully simulated detector. We present our results in this study using the publicly available ATLAS software infrastructure. Based on state-of-the art reconstruction algorithms, a novel analysis of the bb decay could be performed leading to an independent verification of the existing results to an exceptionally high precision.
