Abstract Higgs sectors extended by electroweakly charged scalars can be explored by scalar pair production at the LHC.We consider a fermiophobic scenario, with decays into a Swimwear pair of gauge bosons, and a fermiophilic one, with decays into top and bottom quarks.After establishing the current Artwork bounds on simplified models, we focus on an SU(5)/SO(5) composite Higgs model.
This first exploration demonstrates the need for dedicated searches at current and future colliders.
