|Abstract: ||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.|
