This 2006 book uses the standard model as a vehicle for introducing quantum field theory.

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 physicists of the importance of renormalizable non-Abelian gauge theories of 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 provides a historical account of those discoveries and of the construction and testing of the Standard Model. It also contains a discussion of the future of particle physics and gives an updated status of the LHC and its detectors currently being built at CERN. The book addresses those readers interested in particle physics including the educated public.
