Description

The prospects of the proposed Large Hadron electron Collider (LHeC) in the
search for heavy neutral scalar particles are discussed.
A minimal model is considered with one additional complex scalar singlet that interacts with the Standard Model (SM) via mixing with the Higgs doublet, giving rise to a SM-like Higgs boson h1 and a heavy scalar particle h2.
Both scalar particles are produced via vector boson fusion and can be tested via their decays into pairs of SM particles, analogously to the SM Higgs boson.
Using multivariate techniques we show that the LHeC is sensitive to h2 with masses between 200 and 800 GeV to squared scalar mixings as small as O(0.001).
