Gauge Theories in Particle Physics, Volume II: QCD and the Electroweak Theory, Third Edition(Graduate Student Series in Physics)

"Gauge Theories in Particle Physics Volume 1: From Relativistic Quantum Mechanics to QED" discussed the formulation and application of quantum electrodynamics, which is now regarded as simply the first part of the standard model of particle physics. In volume two the remaining two parts of the standard model, namely, quantum chromodynamics and the electroweak theory of Glashow, Salam and Weinberg are considered. These latter two theories are in some ways like QED but there are important differences, which create significant conceptual and technical difficulties for the student. The aim of the book is to ease the reader through these difficulties, keeping the level of accessibility comparable to that of volume one, and thus provide a much more accessible introduction to these theories than is available elsewhere. As was also the case in volume one, substantial attention is paid to calculations of physical quantities, and to comparison of the resulting predictions with experimental results. The similarities between QED and the two theories studied in volume two include the facts that all three are gauge theories, that the calculation methods of Feynman graphs can be applied to all of them, and that they are all renormalizable. So the foundations of gauge theory, Feynman graphs and renormalization theory laid in volume 1 continue to be highly relevant in volume 2. Nevertheless, there are important differences between QED and the other two theories.
