Production of light Higgs pairs in 2-Higgs doublet models via the Higgs-strahlung process at the LHC
(2010) In Journal of High Energy Physics 2010(11).- Abstract
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 qq̄ (′) → V hh (Higgs-strahlung, V = W ±,Z), in presence of two h → bb̄ 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: λ Hhh - which constrains the form of the Higgs potential - as well as λ W±H∓h and λ ZAh - which are required by gauge invariance. Unfortunately, such claims cannot be extended to the Minimal Supersymmetric... (More)

Unfortunately, such claims cannot be extended to the Minimal Supersymmetric Standard Model, where the extraction of the same signals is impossible.
