Searching for Anomalous Hadronic Higgs Boson Decays at the LHeC — Subhasish Behera, •Manuel Hagelüken, and Matthias Schott — Johannes Gutenberg-Universität Mainz

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, 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 electron-positron colliders. While anomalous hadronic decay signatures of the Higgs boson, e.g. to three or more partons, are difficult to probe at the LHC due to its enormous background rates, it might be possible to search for such decays at the LHeC. In this work, we present the expected sensitivity at the LHeC for H→ 3jets and H→ 4jets decay channels, assumed an integrated luminosity of 1ab⁻¹.
