CEPC Design Report Released

World science, 14 November 2018

Scientists working on the Circular Electron Positron Collider (CEPC), a planned next-generation particle collider in China, officially released its Conceptual Design Report (CDR) today in Beijing.

In a special ceremony at the 2018 CEPC workshop at the Institute of High Energy Physics (IHEP), Prof. Yifang Wang, director of the IHEP and chair of the CEPC steering committee, officially released the CDR to the particle physics community and the public at large.

The two-volume report contains technical details regarding the accelerator (Volume I) and the Physics & Detector (Volume II) of the project. It outlines in great detail the design options of the future collider, which would both complement and go beyond the physics of the Large Hadron Collider at CERN. The report summarizes the work accomplished in the past six years by thousands of scientists and engineers both in China and abroad.

About the CEPC:

After the discovery of the Higgs particle, it is natural to measure its properties as precise as possible, including mass, spin, CP nature, couplings, and etc., at the current running Large Hadron Collider (LHC) and future electron positron colliders, e.g. the International Linear Collider (ILC). The low Higgs mass of ~125 GeV makes possible a Circular Electron Positron Collider (CEPC) as a Higgs Factory, which has the advantage of higher luminosity to cost ratio and the potential to be upgraded to a proton-proton collider to reach unprecedented high energy and discover New Physics.
The CEPC is a circular e+ e-collider located in an underground tunnel of 100-km circumference. The accelerator complex consists of a linear accelerator (Linac), a damping ring, a booster, a collider and several transport lines. The tunnel for such a collider could also host a Super proton proton Collider (SppC) to reach energies beyond the LHC.

The possibility of JINR’s participation in the CEPC project was discussed at the end of 2017 when CEPC SppC accelerator Convener, Professor Jie Gao visited the Joint Institute
