Indirect Probes Of Dynamical Electroweak Symmetry Breaking

The LHC is expected to fid new physics beyond the Standard Model (BSM). Technicolor models are a class of BSM models which involve a new strongly interacting sector responsible for electroweak symmetry breaking (EWSB). The phenomenological viability of these models depends on features such as the existence of an infrared fixed point (IRFP) at strong coupling, and the size of the mass anomalous dimension at this fixed point. As these features are at strong coupling they are not accessible to perturbative methods, and so need to be investigated non-perturbatively using lattice methods. In this thesis, two candidate Technicolor theories are investigated using two independent and complementary lattice methods, the Schrodinger Functional (SF) and the Monte Carlo Renormalisation Group (MCRG), to measure the running of the coupling and the anomalous mass dimension in these theories.

The systematic bottom-up approach provides the appropriate framework for interpreting measurements that will be performed to better understand the physics of mass generation in the universe. No knowledge of quantum field theory is required other than familiarity with effective Lagrangians and Feynmann diagrams.

High Energy Physics 99 contains the 18 invited plenary presentations and 250 contributions to parallel sessions presented at the International Europhysics Conference on High Energy Physics. The book provides a comprehensive survey of the latest developments in high energy physics. Topics discussed include hard high energy, structure functions, soft interactions, heavy flavor, the standard model, hadron spectroscopy, neutrino masses, particle astrophysics, field theory, and detector development.

The authors review models of electroweak symmetry breaking due to new strong interactions at the TeV energy scale and discuss the prospects for their experimental tests. They emphasize the direct observation of the new interactions through high-energy scattering of vector bosons. They also discuss indirect probes of the new interactions and exotic particles predicted by specific theoretical models.
