Abstract

The Standard Model of particle physics is a very successful description of hitherto known physics. However, there are theoretical reasons to expect that the new LHC particle accelerator at CERN finds signs of ’new physics’, physics beyond the Standard Model. Technicolor is one of the most popular alternatives for the new physics. It is very important to know the detailed physical properties of the theory in order to be able to compare the predictions of the theory with the experiments.
Technicolor models rely on so-called strong coupling phenomena, making their study with analytical methods difficult and often impossible. Only large-scale numerical simulations can yield reliable quantitative results; however, so far only very prelimnary studies have been made.
We perform detailed analysis of two technicolor theories, where fermions belong to the symmetric representation of SU(2) or SU(3) gauge group. These are candidates for simplest technicolor models. We study the spectrum of particles predicted by the structure of the theory and the evolution of the coupling constant with the energy scale.
