Chirally Symmetric Technicolor extension to the Standard Model


In this thesis a chirally symmetric technicolor model is investigated as an ex- tension to the Standard model. The extension is based on low-energy QCD, with a linear sigma model used to induce the additional degrees of freedom corresponding to the lightest particles of the new techni-sector. The main goal is to incorporate the SM Higgs into the new model, as to explain its vev and origin within the frame- work of the model. The new model is examined for two cases. First, introducing two new fermions under the new sector; this will be shown to give rise to a possible explanation of the Higgs vev’s origin. Second, three fermions are introduced under the new sector; making for a possible identification of the Higgs as a composite object of the fermions in question.
