Abstract [en]

At the Large Hadron Collider, we prove the feasibility to detect pair production of the lightest CP-even Higgs boson h of a Type II 2-Higgs Doublet Model through the process q (q) over bar ((')) -> V hh ( Higgs-strahlung, V = W-+/-, Z), in presence of two h -> b (b) over bar decays. We also show that, through such production and decay channels, one has direct access to the following Higgs self-couplings, thus enabling one to distinguish between a standard and the Supersymmetric version of the above model: lambda(Hhh) - which constrains the form of the Higgs potential - as well as lambda(W +/- H -/+ h) and lambda(ZAh) - which are required by gauge invariance. Unfortunately, such claims cannot be extended to the Minimal Supersymmetric Standard Model, where the extraction of the same signals is impossible.
