Vector-boson production of light Higgs pairs in 2-Higgs doublet models

At the Large Hadron Collider, we prove the feasibility to detect pair production of the lightest CP-even Higgs boson h of Type II 2-Higgs Doublet Models through qq(') -> qq(')hh (vector-boson fusion). We also show that, through the hh -> 4b decay channel in presence of heavy-flavour tagging, further exploiting forward/backward jet sampling, one has direct access to the lambda Hhh triple Higgs coupling - which constrains the form of the Higgs potential.
