The CEPC Study Group, hosted by the Institute of High Energy Physics (IHEP), has been working on the design and development of a forefront e+e− collider as a Higgs factory that can extend to energies corresponding to the Z, WW and top-quark-pair production, with the upgrade potential to a high-energy pp collider. The CEPC Accelerator Technical Design Report (TDR), which documents the design, the outcomes of the R&D of key technologies, the technical systems, and the cost estimate of the e+e− collider, was released in December, 2023. Going beyond the TDR and preparing CEPC for construction, which may begin in 2027-28, the CEPC Study Group has initialized the Engineering Design Study which will be documented in a formal report (EDR). In 2025, a CEPC proposal will be submitted to Chinese government aiming for CEPC be included into the 15th five year plan.
