Electroweak Precision Tests of Composite Higgs Models




We examine the compatibility of the composite Higgs models with the constraints coming from Electroweak Precision Tests from the low-energy effective theory (EFT) prospective. The EFT approach allows us to capture the common features of the composite Higgs models and incorporate a broad class of explicit models. In our analysis we concentrate on the effects related to a presence of relatively light composite fermionic resonances. We show that some of the typically used observables are non-predictable within the low energy theory and derive the bounds on the parameters of the known explicit models.
