The 2026 International Workshop on the High Energy Circular Electron Positron Collider

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/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
