E-Book Overview
This updated edition of Collider Physics surveys the major developments in theoretical and experimental particle physics and uses numerous illustrations to show how the Standard Model explains the experimental results. Collider Physics offers an introduction to the fundamental particles and their interactions at the level of a lecture course for graduate students, with emphasis on the aspects most closely related to colliders - past, present, and future. It includes expectations for new physics associated with Higgs bosons and supersymmetry. This resourceful book shows how to make practical calculations and serves a dual purpose as a textbook and a handbook for collider physics phenomenology.

Preface
During the last twenty years or so there have been astonishing advances in discovering and understanding the fundamental particles and forces of Nature, from which the universe is built. Even the general public has become aware of this progress, as the news media carry occasional items about the discovery of new quarks or leptons or gauge bosons (names that have come to sound familiar) or about new theories to explain submicroscopic physics. The way was opened by a series of accelerators constructed in many different laboratories around the world to study particle collisions at higher and higher energies. In quantum theory high energies imply short wavelengths, which are essential for probing small-scale phenomena. The latest of these accelerator projects are "colliders," based on the principle of colliding particle beams, which is now the most economical way to achieve the ,highest energies. Future plans are centered o
