Electroweak Theory

I like this book as an excellent introduction and quick guide to electroweak physics. The text is detailed enough to give a clear qualitative explanation of the physical essence and introduce the main concepts and ideas. At the same time it is concise and to the point. There are enough mathematical details to realize what type of calculations are involved, how their logic is, and how they are finally related to experimental data. For some cases you can directly follow the formulas and produce the results yourself. At the same time no cumbersome calculations are presented, instead references are given to the interested reader. I also appreciate a continual accent on the experimental validation of theoretical ideas. Therefore, I would recommend this book to those who need a quick look at electroweak theory in order to have a general idea and decide if they want advanced reading for any particular topic.

electromagnetism. This achievement is comparable to Maxwell's unification of electricity and magnetism. The theory made numerous predictions that have been confirmed by experiments. This book is a concise introduction to the structure of the electroweak theory and its applications. Electroweak Theory describes the structure and properties of field theories with global and local symmetries, leading to the construction of the standard model. The greater part of the book explains the basic predictions of the theory. It describes the new particles and processes predicted by the theory, and compares them with experimental results. Among the topics covered are neutral currents, the properties of W and Z bosons, the properties of quarks and mesons containing heavy quarks, neutrino oscillations, CP-asymmetries in K, D, and B meson decays, and the search for Higgs particles. The book contains sections guiding the reader through the complicated calculations of Feynman diagrams, such as box and penguin diagrams. There are discussions of the results and their relevance to physical phenomena. Each chapter contains selected problems, stemming from the long teaching experience of the author, to supplement the text. This will be of great interest to graduate students and researchers in elementary particle physics.
