Abstract: (arXiv)

The variety of ideas put forward in the context of a 'composite' picture for the Higgs boson calls for a simple and effective description of the related phenomenology. Such a description is given here by means of a 'minimal' model explicitly applied to the case of a Higgs-top sector from an SO(5) symmetry. We discuss the spectrum, the ElectroWeak Precision Tests, flavor and B-physics, LHC phenomenology, and naturalness. The extended gauge sector relative to the standard SU(2)xU(1), if there is any, has little or no impact on these considerations. We also discuss the relation of the 'minimal' model with its 'little Higgs' or 'holographic' extensions based on the same symmetry.
