Singlets in Composite Higgs Models in light of the LHC di-photon searches
Abstract : 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 the Higgs and top partners at the same time. As a prediction, one obtains additional light scalars. We explore the theory space of composite Higgs models and establish if the singlet, from the spontaneous breaking of a U(1) symmetry, is compatible with the recent di-photon excess at 750 GeV at the LHC.
