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 pair of gauge bosons, and a fermiophilic one, with
decays into top and bottom quarks. After establishing the current bounds on
simplified models, we discuss current bounds on various composite Higgs models,
as well as potential discovery channels and search strategies for them.
