Eur.Phys.J.Plus 126:81,2011 We provide a pedagogical introduction to extensions of the Standard Model in
which the Higgs is composite. These extensions are known as models of dynamical
electroweak symmetry breaking or, in brief, Technicolor. Material covered
includes: motivations for Technicolor, the construction of underlying gauge
theories leading to minimal models of Technicolor, the comparison with
electroweak precision data, the low energy effective theory, the spectrum of
the states common to most of the Technicolor models, the decays of the
composite particles and the experimental signals at the Large Hadron Collider.
The level of the presentation is aimed at readers familiar with the Standard
Model but who have little or no prior exposure to Technicolor. Several
extensions of the Standard Model featuring a composite Higgs can be reduced to
the effective Lagrangian introduced in the text. We establish the relevant
experimental benchmarks for Vanilla, Running, Walking, and Custodial
Technicolor, and a natural fourth family of leptons, by laying out the
framework to discover these models at the Large Hadron Collider.
