Minimal walking technicolour — •Dennis Dean Dietrich — Institut für Theoretische Physik, Universität Heidelberg, Heidelberg, Deutschland

In technicolour theories the standard model's elementary Higgs is replaced by a strongly interacting sector. The electroweak symmetry is broken dynamically by chiral symmetry breaking in this sector. Viable theories of this kind must be quasi-conformal and have a small matter content in order to be consistent with electroweak precision data. This can be achieved with techniquarks in higher-dimensional representations of the technicolour gauge group.
