Vector-Boson Production of Light Higgs Pairs in 2-Higgs Doublet Models

Abstract

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 $q{q}^{{(}^{\prime })}\to q{q}^{{(}^{\prime })}hh$ (vector-boson fusion). We also show that, through the $hh\to 4b$ 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.
