Description
Models of compositeness can successfully address the origin of the Higgs boson as a pseudo-Goldstone of a spontaneously broken global symmetry, and flavour physics via the partial compositeness mechanism. If the dynamics is generated by a simple underlying theory defined in terms of a confining gauge group with fermionic matter content, there exists only a finite set of models that have the correct properties to account for a composite Higgs and composite top partners at the same time. As a prediction of these models, one obtains additional light composite scalars. We study the phenomenology of these additional scalars in the light of di-boson resonance searches at LHC.
This presentation is based on JHEP 1511 (2015) 201, arXiv:1512.04508, arXiv:1512.07242, and work to be completed, soon.
