Aspects of dynamical EWSB with a Higgs: from the EFT to concrete models

Dynamical EWSB, although initially conceived for Higgsless models, can easily accommodate a naturally light scalar via different dynamical mechanisms. Assuming that such a mechanism is at work, and quite independent of its detailed nature, the relevant physics at the electroweak scale can be described in terms of an EFT. In the first part of this talk I will discuss the systematics of such an EFT and its phenomenological implications in view of the next runs at the LHC. In the second part I will review some of the most relevant dynamical mechanisms that can make the Higgs naturally light within this framework and show how they can be realized through specific models.
