Book Description
I review the array of event generators which have been written to provide simulations of high-energy ee− reactions. In this report, I have tried to summarize the array of programs that are now available to perform event generation for LC physics. These range from the general-purpose generators PYTHIA and HERWIG, to specific tools for super-symmetry and multi-fermion simulations, to tools for automatic generation of events for arbitrary physics processes. For the future, we expect to see trends toward object-oriented and modular programs, toward detailed high-accuracy computation of standard background processes, and toward further automation of complex calculations. We are well on the way to the level of accuracy and generality that will be needed for the LC physics program.

Book Description
The International Linear Collider (ILC) is a mega-scale, technically complex project, requiring large financial resources and cooperation of thousands of scientists and engineers from all over the world. Such a big and expensive project has to be discussed publicly, and the planned goals have to be clearly formulated. This book advocates for the demand for the project, motivated by the current situation in particle physics. The natural and most powerful way of obtaining new knowledge in particle physics is to build a new collider with a larger energy. In this approach, the Large Hadron Collider (LHC) was created and is now operating at the world record center of-mass energy of 13 TeV. Although the design of colliders with a larger energy of 50-100 TeV has been discussed, the practical realization of such a project is not possible for another 20-30 years. Of course, many new results are expected from LHC over the next decade. However, we must also think about other opportunities, and in particular, about the construction of more dedicated experiments. There are many potentially promising projects, however, the most obvious possibility to achieve significant progress in particle physics in the near future is the construction of a linear e+e- collider with energies in the range (250-1000) GeV. Such a project, the ILC, is proposed to be built in Kitakami, Japan. This book will discuss why this project is important and which new discoveries can be expected with this collider.

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
Collider experiments have become essential to studying elementary particles. In particular, lepton collisions such as e⁺e⁻ are ideal from both experimental and theoretical points of view, and are a unique means of probing the new energy region, sub-TeV to TeV. It is a common understanding that a next-generation e⁺e⁻ collider will have to be a linear machine that evades beam-energy losses due to synchrotron radiation. In this book, physics feasibilities at linear colliders are discussed in detail, taking into account the recent progress in high-energy physics.

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.

Book Description
Market: Physicists, especially beam physicists and elementary particle physicists, as well as science historians and students. In the 1950s and 60s a revolution took place in our ability to handle and manipulate particle beams. This revolution cleared a path for major advances and changed forever the way matter is explored at the subnuclear level. This volume gathers together for the first time the seminal papers on the development and expansion of collider physics. Included are groundbreaking writings from Gersh Budker, Donald Kerst, Bruno Touschek, Nobel laureate Simon van der Meer, Gerry O'Neill, Ernest Courant, Keith Symon, and others. The editors, Claudio Pellegrini and Andrew Sessler, were colleagues of many of these notable contributors and witnesses to the development of virtually every machine mentioned in the book.

Book Description
The idea of colliding two particle beams to fully exploit the energy of accelerated particles was first proposed by Rolf Wideröe, who in 1943 applied for a patent on the collider concept and was awarded the patent in 1953. The first three colliders — AdA in Italy, CBX in the US, and VEP-1 in the then Soviet Union — came to operation about 50 years ago in the mid-1960s. A number of other colliders followed.Over the past decades, colliders defined the energy frontier in particle physics. Different types of colliers — proton-proton, proton-antiproton, electron-positron, electron-proton, electron-ion and ion-ion colliders — have played complementary roles in fully mapping out the constituents and forces in the Standard Model (SM). We are now at a point where all predicted SM constituents of matter and forces have been found, and all the latest ones were found at colliders. Colliders also play a critical role in advancing beam physics, accelerator research and technology development. It is timely that RAST Volume 7 is dedicated to Colliders.

Book Description
We review the physics basis, main features and use of general-purpose Monte Carlo event generators for the simulation of proton-proton collisions at the Large Hadron Collider. Topics included are: the generation of hard-scattering matrix elements for processes of interest, at both leading and next-to-leading QCD perturbative order; their matching to approximate treatments of higher orders based on the showering approximation; the parton and dipole shower formulations; parton distribution functions for event generators; non-perturbative aspects such as soft QCD collisions, the underlying event and diffractive processes; the string and cluster models for hadron formation; the treatment of hadron and tau decays; the inclusion of QED radiation and beyond-Standard-Model processes. We describe the principal features of the Ariadne, Herwig++, Pythia 8 and Sherpa generators, together with the Rivet and Professor validation and tuning tools, and discuss the physics philosophy behind the proper use of these generators and tools. This review is aimed at phenomenologists wishing to understand better how parton-level predictions are translated into hadron-level events as well as experimentalists wanting a deeper insight into the tools available for signal and background simulation at the LHC.
