Negative S parameter in Holographic Technicolor

Technicolor faces a technical challenge: the difficulty of computing observables for strongly-interacting theories. This is made worse by the fact that technicolor models should depart from QCD by more than a simple Nc-rescaling, as required by experimental tests. Based on the experience gathered from Holographic QCD in the last two years, we resort to 5D models in order to predict the dependence of electroweak observables on the size and dimension of condensates.
