Phenomenologically Viable Dynamical Electro-Weak Symmetry Breaking

The lack of deviations from the Standard Model at the current level of experimental precision can be explained systematically in suitable models of dynamical electro-weak symmetry breaking. The key ingredient is dynamics which produces a scalar unitarity partner for the Goldstone-Bosons and which leads to a decoupling of effects beyond the Standard Model. A phenomenologically successful left-right symmetric model is presented from this point of view.
