From Current Algebra to Quantum Chromodynamics

The advent of quantum chromodynamics (QCD) in the early 1970s was one of the most important events in twentieth-century science. This book examines the conceptual steps that were crucial to the rise of QCD, placing them in historical context against the background of debates that were ongoing between the bootstrap approach and composite modeling, and between mathematical and realistic conceptions of quarks. It explains the origins of QCD in current algebra and its development through high-energy experiments, model-building, mathematical analysis and conceptual synthesis. Addressing a range of complex physical, philosophical and historiographical issues in detail, this book will interest graduate students and researchers in physics and in the history and philosophy of science. Review of the hardback: 'Tian Yu's book is a penetrating treatment of the physics involved, but with many philosophical asides, that he alone can produce effortlessly. I have enjoyed reading it enormously.' Michael Redhead, Professor Emeritus, University of Cambridge, FBA 'Cao's book provides many historical and conceptual insights into the fascinating development of QCD.'
