We discuss models in which vectorlike quarks and a second Higgs doublet are simultaneously present and couple to the third generation of SM quarks. A general feature of these models is that cascade decays of vectorlike fermions into heavy Higgses (or vice versa, depending on their masses) dominate their respective branching ratios. The resulting collider signals involve a large multiplicity of b-jets and offer formidable experimental challenges. We present a detailed and realistic analysis of the expected sensitivity of dedicated searches at ATLAS and CMS.
