Introduction to the Physics of Electroweak Interactions is a six-chapter book that first elucidates the deep-inelastic and elastic lepton scattering on nucleons (both cases of polarized and nonpolarized initial particles). Subsequent chapter presents a brief history of the construction of the phenomenological V-A weak interaction Hamiltonian. Other chapters detail the Glashow-Weinberg-Salam unified theory of weak and electromagnetic interactions; the processes in which neutrinos take part; and processes due to neutral currents, deep-inelastic neutrino-nucleon scattering, elastic neutrino-nucleon scattering, and elastic neutrino-electron scattering. This book will be useful to those who wish to master the techniques for calculating the experimentally measured quantities.

A graduate-level description of how the theory of electroweak interactions, or so-called "Standard Model" unifies the weak and electromagnetic forces of nature in high energy physics.

Get First-Hand Insight from a Contributor to the Standard Model of Particle PhysicsWritten by an award-winning former director-general of CERN and one of the world's leading experts on particle physics, Electroweak Interactions explores the concepts that led to unification of the weak and electromagnetic interactions. It provides the fundamental el

The papers contained in this volume are invited lec tures presented at the 21st "Universit~tswochen fUr Kern physik" in Schladming in February 1982. To consider electro magnetic and weak interactions as manifestations of a single theory is a standpoint, which is generally accepted by now. The goal of the school was to outline the present state of this unified theory and to discuss possible future developments. Thanks to the generous support provided by the Austrian Ministry of Science and Research, the Styrian Government and other sponsors, it was again possible to invite experts in the field as lecturers. The lecture notes have been reexamined by the authors and are now published in their final form to enable a larger number of physicists to profit from them. Since the lectures are already quite voluminous, we have decided to restrict the publication to the lectures themselves and omit all seminars, interesting as they were, as well as all details connected with the meeting. It is a pleasure to thank all the lecturers for their efforts, making it possible to speed up publication. Thanks are also due to L. Pittner for organisation and proof-reading as well as to Mrs. Krenn and Mrs. Neuhold for the careful typing of the papers. H. Mitter Acta Physica Austriaca, Suppl.

This volume contains the contributions of 47 leading researchers in high energy physics, both theorists and experimentalists, from all over the world. It discusses the application of quantum field theory to phenomenology in all areas of active research in particle physics. The topics covered include: (i) the status of precision measurements at LEP, SLC, HERA, Tevatron, and other experiments; (ii) quantum-field-theoretical techniques for calculating electroweak and QCD radiative corrections; and (iii) radiative corrections and precision experiments in future colliders (Tevatron II, LHC, NLC, Muon Collider, etc.). The confrontation in a single volume of all the high precision results reported by experimentalists, on one side, with the predictions of the Standard Model (SM) at the level of radiative corrections, on the otherside, provides a detailed test of the SM at the quantum level. And, where discrepancies appear, it gives hints of physics beyond the SM (such as supersymmetry, effective quantum field theories, etc.) which are thoroughly discussed in the book.
