Resumo: The radial excitation of the global symmetry-breaking vacuum in composite Higgs models, called the global Higgs, has been recently a focus of investigation. In this paper we study the prospects for detecting this composite scalar at the 13TeV LHC. We compute the global Higgs production rates and estimate the discovery potential of a global Higgs decaying into top quark pairs and into Higgs and electroweak gauge bosons with subsequent hadronic decays. The global Higgs may also decay into fermion resonances such as top partners, providing a new window into compositeness. We show that top partner jets can be effectively unresolved in some regions of the parameter space. Such boosted top partner signatures would deserve the development of dedicated substructure analyses.
