Abstract Since the discovery of the Higgs in 2012, the features of the SM are being completed. The solution of the hierarchy problem mentioned above has typically two approaches: if the Higgs boson is elementar, the supersymmetry must be present on the TeV scale. Otherwise, Higgs is a composite state. At these project we focus on in the last case.The composite Higgs model needs, in general, the existence of new particles on the scale of TeV. Since in these models Higgs is a pseudo Nambu-Goldstone Boson resulting of the spontaneous global symmetry breaking, those new states stem from a new symmetry and appear to be inevitable. The absence of detection of those states, mainly at LHC, is a problem from the models of composite Higgs. The goal of these project is to understand the phenomenology and the theoretical bases of these models. | |
