The 2025 International Workshop on the High Energy Circular Electron Positron Collider (CEPC2025) will take place in Guangzhou, November 6-10, 2025, co-hosted by South China Normal University and the Institute of High Energy Physics, CAS.

The CEPC study group has released the Technical Design Report (TDR) on the accelerator and is progressing toward the Engineering Design Report (EDR). Additionally, the group plans to release a TDR for a reference detector in 2025. This workshop aims to bring together scientists worldwide to explore the physics potential of the CEPC, enhance international collaboration on optimizing the accelerator and detectors, and advance R&D on critical technologies. Moreover, discussions on industrial partnerships for technology R&D and industrialization preparation will be included.

The workshop program will feature plenary, parallel, and poster sessions. All plenary presentations will be invited talks, while posters will be selected from submitted abstracts. Parallel session presentations will be drawn from both sources. The workshop encourages participation, particularly from graduate students and postdocs.

Poster presenters, please follow the instructions. Outstanding posters will receive awards, selected by a committee comprising SPC members, session conveners, and local organizers.
