In this dissertation, we revisit the prospects of a strongly interacting theory for the Electroweak Symmetry Breaking Sector
of the Standard Model, after the discovery of a Higgs-like boson at 125GeV. As the LHC constrains new phenomena near the Higgs
mass, it is natural to assume that the new scale is of order 1TeV. This mass gap might indicate strongly interacting new physics.
This work is of quite general validity and model independence. With only a few parameters at the Lagrangian level, multiple
channels (possibly with new physics resonances) are describable, and many BSM theories can be treated. It will be of interest
to postgraduate students and researchers, and is accessible to newcomers in the field. Many calculations are given in full
detail and there are ample graphical illustrations.
