Description
LHC experiments have essentially ruled out the existence of additional chiral fermions. Thus, new elementary fermions must be vectorlike with respect to the SM gauge interactions. LHC searches for vectorlike quarks typically focus on their mixing-induced decays into W, Z and Higgs bosons. In this talk, I will point out that vectorlike quarks may instead manifest themselves in events with 6 or more top quarks, if the vectorlike quark interacts with a complex scalar field. For a region of parameter space the dominant LHC signal in such a model is 8 tops. The ensuing signals would be spectacular, including many leptons and b jets.
