Book Description
This up-to-date volume reviews the recent contributions of electron-positron colliders to the precision test of the electroweak Standard Model. In particular, it contains a short summary of the measurements at the Z resonance and gives an overview of the electroweak processes above the Z. Subsequently, the measurement of the W mass at LEP is discussed in detail. The implications for the precision test of the Standard Model are presented, giving the status of the global electroweak fit before the startup of Large Hadron Collider. The final chapters give an outlook on the electroweak physics at a future linear collider. The book also features many illustrations and tables. Readers obtain a coherent overview of the results of 20 years of electroweak physics conducted at electron-positron colliders.

Book Description
During more than 10 years, from 1989 until 2000, the LEP accelerator and the four LEP experiments, ALEPH, DELPHI, L3 and OPAL, have taken data for a large amount of measurements at the frontier of particle physics. The main outcome is a thorough and successful test of the Standard Model of electroweak interactions. Mass and width of the Z and W bosons were measured precisely, as well as the Z and photon couplings to fermions and the couplings among gauge bosons. The rst part of this work will describe the most important physics results of the LEP experiments. Emphasis is put on the properties of the W boson, which was my main research eld at LEP. Especially the precise determination of its mass and its couplings to the other gauge bosons will be described. Details on physics effects like Colour Reconnection and Bose-Einstein Correlations in W-pair events shall be discussed as well. A conclusive summary of the current electroweak measurements, including low-energy results, as the pillars of possible future ndings will be given. The important contributions from Tevatron, like the measurement of the top quark and W mass, will round up the present day picture of electroweak particle physics. This is an open access book.

Book Description
This book provides a comprehensive summary of studies of the Z boson in electron positron interactions. The results that have been obtained have achieved unprecedented accuracy and have firmly established the Electroweak Standard Model as the cornerstone of our current understanding of modern particle physics. The book introduces the background to the Standard Model and the role of the Z boson and describes briefly the accelerators and experiments involved in these results. The five main chapters deal with the detailed measurements of the electroweak parameters of the Z, the study of QCD, heavy quark physics, tau lepton physics and the search for new particles. Each chapter ends with a summary and outlook to prospects of future accelerators. Most of the results are from the first six years running at the first phase of electron positron collider, LEP, at energies corresponding to the Z mass, but results from the SLAC Linear Collider and some new results at higher energies are also included.

Book Description
This workshop brought together for the first time accelerator experts as well as experimental and theoretical high energy physicists from all over the world to consider the physics potential of high energy linear electron-positron colliders. A wide variety of physics cases were presented ranging from precision tests of the top quark and electroweak gauge bosons to searches of the intermediate mass Higgs bosons and supersymmetric particles.

Book Description
The high energy electron-positron linear collider is expected to provide crucial clues to many of the fundamental questions of our time: What is the nature of electroweak symmetry breaking? Does a Standard Model Higgs boson exist, or does nature take the route of supersymmetry, technicolor or extra dimensions, or none of the foregoing? This invaluable book is a collection of articles written by experts on many of the most important topics which the linear collider will focus on. It is aimed primarily at graduate students but will undoubtedly be useful also to any active researcher on the physics of the next generation linear collider. Contents:The Machine and Detector (G A Blair & D J Miller)Higgs Physics at the Linear Collider (J F Gunion et al.)Top Quark Physics (Y Sumino)Supersymmetry and the Linear Collider (J L Feng & M M Nojiri)Dynamical Electroweak Symmetry Breaking (W Kilian)Physics of Electroweak Gauge Bosons (K Mönig)New Physics at the TeV Scale and Beyond (J L Hewett)QCD (P N Burrows)Gamma-Gamma and Other Options (T Takahashi)CP Violation at the Linear Collider (D Atwood & A Soni)Overall Perspective (K Fujii & M E Peskin) Readership: Researchers in high energy, particle and accelerator physics.

Book Description
The book discusses the recent experimental results obtained at the LHC that involve electroweak bosons. The results are placed into an appropriate theoretical and historical context. The work pays special attention to the rising subject of hadronically decaying bosons with high boosts, documenting the state-of-the-art identification techniques and highlighting typical results. The text is not limited to electroweak physics in the strict sense, but also discusses the use of electroweak vector-bosons as tool in the study of other subjects in particle physics, such as determinations of the proton structure or the search for new exotic particles. The book is particularly well suited for graduate students, starting their thesis work on topics that involve electroweak bosons, as the book provides a comprehensive description of phenomena observable at current accelerators as well as a summary of the most relevant experimental techniques.

Book Description
Understanding of protons and neutrons, or "nucleons"â€"the building blocks of atomic nucleiâ€"has advanced dramatically, both theoretically and experimentally, in the past half century. A central goal of modern nuclear physics is to understand the structure of the proton and neutron directly from the dynamics of their quarks and gluons governed by the theory of their interactions, quantum chromodynamics (QCD), and how nuclear interactions between protons and neutrons emerge from these dynamics. With deeper understanding of the quark-gluon structure of matter, scientists are poised to reach a deeper picture of these building blocks, and atomic nuclei themselves, as collective many-body systems with new emergent behavior. The development of a U.S. domestic electron-ion collider (EIC) facility has the potential to answer questions that are central to completing an understanding of atoms and integral to the agenda of nuclear physics today. This study assesses the merits and significance of the science that could be addressed by an EIC, and its importance to nuclear physics in particular and to the physical sciences in general. It evaluates the significance of the science that would be enabled by the construction of an EIC, its benefits to U.S. leadership in nuclear physics, and the benefits to other fields of science of a U.S.-based EIC.
