能量前沿正负电子对撞机的研究进展
摘要
In 2012, the discovery of a particle matching the Higgs boson at CERN's Large Hadron Collider became a very important milestone in high energy physics history. Research and development towards future high-energy electron-positron colliders is actively explored around the world with the purpose of measuring precisely the properties of this unconfirmed Higgs boson and to discover new physics beyond the Standard Model of particle physics. In this paper, we briefly review the history from the past half century of electron-positron colliders at the high-energy frontier, including the first electron-positron collider AdA, as well as the colliders based AdA, such as ACO, VEPP-II, ADONE, and the later colliders SPEAR, DORIS, CESR, TRISTAN etc., and the last and largest electron-positron collider in the world up to now, LEP. Then, the paper reports several proposals for future electron-positron colliders from around the world such as ILC, CLIC TLEP and so on, in particular China's entry, the Circular Electron-Positron Collider.
