International Linear Collider (ILC)

The natural and most powerful way of obtaining new knowledge in particle physics is to build a new collider with a larger energy. To this end, 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 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 of 250–1000 GeV. Such a project, the International Linear Collider, 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.
