Fundamentals Of Electroweak Theory (Second Edition)
This book is based on the lecture course taught by the author for about three decades at Charles University. The author gives a thorough and easy-to-read account of the basic principles of the standard model of electroweak interactions, describes various theories of electromagnetic and weak interactions, and explains the gauge theory of electroweak interactions. The criterion of the tree-level unitarity is used throughout the text to check the gradual steps leading to the renormalizable electroweak theory. Five appendices expound on some special techniques of the Standard Model, used in the main body of the text.The book can be read with just a preliminary knowledge of quantum field theory. In comparison with the first edition of the book published more than 20 years ago, new passages concerning the Higgs boson are added, as well as some new problems and solutions.
Fundamentals of Electroweak Theory
Fundamentals of Electroweak Theory provides a comprehensive introduction to the principles and concepts underlying the electroweak theory in particle physics. This book covers the fundamental interactions between electromagnetic and weak nuclear forces, describing the theoretical framework developed to explain phenomena such as particle decay and scattering processes. Through mathematical formalism and theoretical insights, readers gain an understanding of the symmetry breaking mechanism, gauge theory, and the Higgs mechanism, which are central to the formulation of the electroweak theory. Whether you're a student, researcher, or enthusiast in the field of particle physics, Fundamentals of Electroweak Theory serves as an essential resource for delving into the theoretical foundations of this fundamental aspect of the Standard Model of particle physics.
Electroweak Symmetry Breaking
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.
