Electroweak Symmetry Breaking

Beschreibung

With this thesis the author contributes to the development of a nonmainstreambut long-standing approach to electroweak symmetry breakingbased on an analogy with superconductivity. Electroweak symmetrybreaking is assumed to be caused by dynamically generated masses oftypical fermions, i.e., of quarks and leptons, which in turn assumes a newdynamics between quarks and leptons. Primarily it is designed to generatefermion masses, and electroweak symmetry breaking is an automaticconsequence..the summary of the topic, the first main part of the thesis addressesthe question as to whether the masses of known quarks and leptons providesufficiently strong sources of electroweak symmetry breaking. It isdemonstrated that neutrino masses subject to the seesaw mechanism areindispensable ingredients. The other two parts of the thesis are dedicatedto the presentation of two particular models: The first model is based onthe new strong Yukawa dynamicsand serves as a platform for studyingthe ability to reproduce fermion masses. The second, more realistic modelintroduces a flavor gauge dynamics and its phenomenological consequencesare studied.Although interest in this type of model has waxed and waned over theyears, following the discovery of the Standard-Model-like Higgs particle,it is regaining its relevance.Although interest in this type of model has waxed and waned over theyears, following the discovery of the Standard-Model-like Higgs particle,it is regaining its relevance.Although interest in this type of model has waxed and waned over theyears, following the discovery of the Standard-Model-like Higgs particle,it is regaining its relevance.

With this thesis the author contributes to the development of a non-mainstream but long-standing approach to electroweak symmetry breaking based on an analogy with superconductivity. Electroweak symmetry breaking is assumed to be caused by dynamically generated masses of typical fermions, i.e., of quarks and leptons, which in turn assumes a new dynamics between quarks and leptons. Primarily it is designed to generate fermion masses and electroweak symmetry breaking is an automatic consequence.

After the summary of the topic, the first main part of the thesis addresses the question as to whether the masses of known quarks and leptons provide sufficiently strong sources of electroweak symmetry breaking. It is demonstrated that neutrino masses subject to the seesaw mechanism are indispensable ingredients. The other two parts of the thesis are dedicated to the presentation of two particular models: The first model is based on the new strong Yukawa dynamics and serves as a platform for studying the ability to reproduce fermion masses. The second, more realistic model introduces a flavor gauge dynamics and its phenomenological consequences are studied.

Even though, in the past, this type of models has already been of some interest, following the discovery of the Standard-Model-like Higgs particle, it is regaining its relevance.
