Precision Tests Of The Standard Electroweak Model


Book Description

High precision measurements of weak neutral current and charged current processes and of the properties of the Z and W bosons have established the standard electroweak model as correct down to a distance scale of 10-16 cm, and are a sensitive probe of possible underlying physics. In this book, all aspects of the program are considered in detail, including the structure of the standard model, radiative corrections, high precision experiments, and their implications. The major classes of experiments are surveyed, covering the experiments themselves, the data analysis, results, and prospects.This volume is a detailed reference for theoretical and experimental researchers, as well as an introductory text for advanced students.




Electroweak Effects at High Energies


Book Description

The first Europhysics Study Conference on Electroweak Effects at High Energies was held at the "Ettore Majorana" Centre for Scientific Culture in Erice, Sicily from February 1 -12, 1983. The conference was attended by 61 physicists from 11 countries. The conference was sponsored by the European Physical Society, the Italian Ministry of Public Education, the Italian Ministry of Technological Research, the Sicilian Regional Government and the California Institute of Technology. CONFERENCE FORMAT The Study Conference followed a new intensive format in which the state of our knowledge of the electroweak interaction, and the relation of the electroweak sector to Grand Unified and Superunified Theories was reviewed in some depth. During the two week conference, 54 experimental and theoretical talks were presented, and four evening discussion sessions were held. The Erice surroundings, the wide-ranging conference program, and the fact that nearly all of the participants were directly involved in recent major experimental or theoretical developments, led to animated and very friendly discussions. Participants had the rare opportunity to view most of the major trends in high energy physics in a short interval of time, and to discuss and contemplate the trends in the uniquely peaceful yet stimulating atmosphere which is an Erice tradition.




Theory of Precision Electroweak Measurements


Book Description

In these lectures, I will review the theoretical concepts needed to understand the goals and implications of experiments in this new era of weak interactions. I will explain how to compute the most important order-[alpha] radiative corrections to weak interaction processes and discuss the physical implications of these correction terms. I hope that this discussion will be useful to those -- experimentalists and theorists -- who will try to interpret the new data that we will soon receive. This paper is organized as follows: I will review the structure of the standard weak interaction model at zeroth order. I will discuss the measurement of the Z° boson mass in ee− annihilation. This measurement is affected by radiative correction to the form of the Z° resonance, and so I will review the theory of the resonance line shape. I will briefly review the modifications of the properties of the Z° which would be produced by additional neutral gauge bosons. I will review the theory of the renormalization of weak interaction parameters such as sin2 [theta]{sub {omega}}, concentrating especially on the contributions of the top quark and other heavy, undiscovered particles.




Precision Tests Of The Standard Model At High Energy Colliders - Proceedings Of The Xviii International Meeting On Fundamental Physics And Xxi G.i.f.t. International Seminar On Theoretical Physics


Book Description

This proceedings focuses on the theoretical and experimental status of the Standard Model of the strong and electroweak interactions. They are discussed in the light of recent experimental results from high energy e+e- and hadron colliders.




Electroweak Precision Tests at LEP


Book Description

This review gives a brief discussion of the structure of the Standard Model and its quantum corrections. The predictions for the vector boson masses, the neutrino scattering cross-sections and the Z0 resonance observables are presented. The influence of virtual new physics effects on the observables is discussed with the minimal supersymmetric Standard Model taken as an example. Experimental measurements of electroweak observables are described with reference to studies performed at the e+e- collider LEP at energies close to the Z0 peak. The theoretical predictions are compared with experimental data and their implications for the Standard Model are discussed.

EPS - High Energy Physics '89


Book Description

EPS - High Energy Physics '89 presents the proceeding of the International Europhysics Conference on High Energy physics, held in Madrid, Spain, on September 6–13, 1989. This book outlines several topics on the interface between cosmology/astrophysics and particle physics. Organized into two parts encompassing 181 chapters, this compilation of papers begins with an overview of the implications of the cosmic light element abundances. This text then examines the various aspects of lattice field theory. Other chapters consider the theoretical evidence of a fundamental length in string theory and outline the main features of the higher order corrections to the heavy quark inclusive cross section. This book discusses as well the theory of heavy quark production in hadron collision. The final chapter deals with the idea of low-energy supersymmetry, which relates the scale of supersymmetry breaking to the origin and stability of the electroweak scale. This book is a valuable resource for astrophysicists, physicists, and scientists.
