The “Physics in Collision” conference aims to provide an overview of the main topics of high energy physics. This annual international meeting consists of three days of exclusive review talks, given by invited speakers. As a result, it has taken on a unique character, ideal for those who wish to be brought up to date on the current status of particle physics.
This book consists of a collection of carefully selected review papers and lecture notes written by the author on Perturbative Quantum Chromodynamics (PQCD) and its experimental tests. A leading authority who has contributed significantly to the development of PQCD for more than 20 years, the author has selected articles on the basis of their present interest. These articles cover different aspects of the subject without unnecessary duplication and are accompanied by commentaries. Also, original material, specially written for this book, has been added to integrate and update the results and their presentation. Hence, more than providing a historical perspective on the subject, this volume also serves well as an authoritative guidebook on Perturbative QCD.
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.
The second course of the International School on Physics with Low Energy Antiprotons was held in Erice, Sicily at the Ettore Majorana Centre for Scientific Culture, from May 20 to May 31, 1987. The School is dedicated to physics accessible to experiments using low energy antiprotons, especially in view of operation of the LEAR facility at CERN with the upgraded antiproton source AAC (Antiproton Accumulator AA and Antiproton Collector ACOL). The first course in 1986 covered topics related to fundamental symmetries. This book contains the proceedings of the second course which focused on spectroscopy of light and heavy quarks. These proceedings contain both the tutorial lectures and contri butions presented by participants during the School. The papers are organized in four sections: The first section includes theoretical reviews. Section II contains experimental reviews and covers the results in meson spectroscopy from DM2, MARK III, GAMS and n-WA76. Section III presents the new meson spectroscopy experiments in pre paration at CERN and Fermilab: Crystal Barrel, OBELIX, Jetset and E760. Section IV is dedicated to LEAR and to future facilities where meson spectroscopy would be a principal component of the physics programme. We should like to thank Dr. Alberto Gabriele and the staff of the Ettore Majorana Centre who provided for a smooth running of the School and a very pleasant stay. We are particularly grateful to Mrs. Anne Marie Bugge for her crucial help during the preparation and running of the School and for the editing of these Proceedings.
The discoveries of neutral currents and of the W and Z bosons marked a watershed in the history of CERN. They established the validity of the electroweak theory and convinced the physicists of the importance of renormalizable non-Abelian gauge theories of the fundamental interactions. The articles collected in this book have been written by distinguished physicists who contributed in a crucial way to these developments. The book is a historical account of those discoveries and of the construction and the testing of the standard model. It also reports on the future of particle physics and provides an updated status report on the LHC and its detectors being currently built at CERN. The book addresses readers interested in particle physics including the educated public.
This is a selection from over 250 papers published by Abdus Salam. Professor Salam has been Professor of Theoretical Physics at Imperial College, London and Director of the International Centre for Theoretical Physics in Trieste, for which he was largely responsible for creating. He is one of the most distinguished theoretical physicists of his generation and won the Nobel Prize for Physics in 1979 for his work on the unification of electromagnetic and weak interactions. He is well known for his deep interest in the development of scientific research in the third world (to which ICTP is devoted) and has taken a leading part in setting up the Third World Academy. His research work has ranged widely over quantum field theory and all aspects of the theory of elementary particles and more recently into other fields, including high-temperature superconductivity and theoretical biology. The papers selected represent a cross section of his work covering the entire period of 50 years from his student days to the present.
