Description

Composite Higgs Models vary the strong symmetry breaking paradigm by interpolating between simple Technicolor theories and the Higgs model: The Higgs boson emerges as the bound state of a strongly interacting sector, rather than being an elementary field. Its couplings deviate from that of an elementary Standard Model (SM) Higgs boson. Composite Higgs models are therefore seriously constrained by electroweak precision data. Further constraints arise from direct searches for new fermions, from the measurement of $V_{tb}$ and from the LHC Higgs data. In this talk I will present the idea of composite Higgs models. Their compatibility with the available experimental data is investigated. Possible tests of the composite Higgs realization are presented. They are necessary in order to answer the question if the mechanism beyond electroweak symmetry breaking is weakly interacting as in the SM or if it is based on a strong dynamics as in composite Higgs models.
