Motivated by dramatic developments in the field, this book provides a thorough introduction to spin and its role in elementary particle physics. Starting with a simple pedagogical introduction to spin and its relativistic generalisation, the author avoids the obscurity and impenetrability of traditional treatments of the subject. The book surveys the main theoretical and experimental developments, as well as discussing exciting plans for the future. Emphasis is placed on the importance of spin-dependent measurements in testing QCD and the Standard Model. This book will be of value to graduate students and researchers working in all areas of quantum physics and particularly in elementary particle and high energy physics. It is suitable as a supplementary text for graduate courses in theoretical and experimental particle physics. This title, first published in 2001, has been reissued as an Open Access publication on Cambridge Core.

The revolution in elementary particle physics sparked by the unearthing of the bizarre J/psi particle in 1974, and followed by the discovery of the equally mysterious tau and upsilon particles, led to a beautiful interweaving of theory and experiment culminating in the SalamWeinberg theory of electroweak interactions and the Quantum Chromodynamic theory of strong interactions. The extraordinary prediction of the existence of the W and Z-zero bosons was fulfilled in 1983, and it is now possible to produce Z-zeros in millions. The emphasis today is on fine quantitative detail and, to match this, more sophisticated theoretical calculations are demanded. This book presents a comprehensive and unified treatment of modern theoretical and experimental particle physics at a level accessible to beginning research students. The emphasis throughout, is on presenting underlying physical principles in a simple and intuitive way.

This work presents, in two volumes, a comprehensive and unified treatment of modern theoretical and experimental particle physics at a level accessible to beginning research students. The emphasis throughout is on presenting underlying physical principles in a simple and intuitive way, and the more sophisticated methods demanded by present day research interests are introduced in a very gradual and gentle fashion. Volume 1 covers electroweak interactions, the discovery and properties of the 'new' particles, the discovery of partons and the construction and predictions of the simple parton model. Volume 2 deals at some length with CP-violation, but is mainly devoted to QCD and its application to 'hard' processes. A brief coverage of 'soft' hadronic physics is included. This work will provide a comprehensive reference and textbook for all graduate students and researchers interested in modern particle physics.
