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 Standard Model, where the extraction of the same signals is impossible.
