The 2026 International Workshop on the High-Energy Circular Electron-Positron Collider (CEPC2026) will be held in Shanghai from October 22 to 26, 2026. The event is jointly hosted by Fudan University (FDU), the Shanghai Institute of Ceramics (SIC/CAS), and the Institute of High Energy Physics (IHEP of CAS). This annual workshop brings together scientists from around the world to explore the physics potential of future high-energy circular electron-positron colliders . It fosters international collaboration to optimize accelerator and detector designs, and advances R&D on critical technologies.
The workshop will feature plenary, parallel, and poster sessions. All plenary presentations will be invited talks, while poster presentations will be selected from submitted abstracts. Parallel session talks will be drawn from both invited speakers and submitted abstracts. We especially encourage participation from graduate students and postdocs. Outstanding posters will be recognized with awards, chosen by a selection committee composed of Scientific Program Committee (SPC) members, session conveners, and local organizers.
The program will also showcase exhibitions by leading industrial partners, offering attendees a firsthand look at cutting-edge innovations and advanced prototypes, along with focused discussions on technology research and development, and strategies for industrialization readiness.
Deadline for abstract submission is September 6, 2026. Deadline for registration is September 30, 2026. For information about visa applications, please visit the dedicated page at https://indico.ihep.ac.cn/event/20099/, which is also accessible via the registration page.
