Vision for High-Energy-Frontier Particle Colliders in China

The discovery of the Higgs boson at the Large Hadron Collider has opened the door to a new realm of physics, where high-energy accelerators are essential to explore more fundamental laws. In this article, we share our vision regarding the future of high-energy physics and accelerators, particularly focusing on the Circular Electron Positron Collider (CEPC) and Super Proton-Proton Collider (SPPC) projects proposed by Chinese scientists in September 2012. Following the recent completion of the CEPC accelerator's technical design report, we review its main physics drives, technical design, and related technology development. The construction of the CEPC will become technologically viable upon the completion of its engineering design report, expected in approximately 3 years. Efforts are also underway to advance technologies for the SPPC.
