Description
The Future Circular Collider Project – Reference Design Phase
Dr. Frank Zimmermann, CERN / Switzerland
The Future Circular electron–positron Collider (FCC-ee) is designed as a highest-luminosity Higgs-boson, electroweak, and top-quark factory. The FCC-ee could be followed, as a potential second step, by a highest-energy proton–proton collider (FCC- hh), installed in the same tunnel. The 2025/26 European Strategy Update has recommended the FCC as the preferred option for the next flagship collider at CERN. Since January 2026, the FCC project has entered the Reference Design Phase (RDP) aimed at enabling possible project approval by CERN Council in 2028.In this seminar, I first review a few key results from the 2021-2025 FCC Feasibility Study,including key concepts, local implementation, civil engineering, and global collaboration,then report recent evolutions of the accelerator design and examples of technologydevelopment, and, finally, present the next RDP milestones and overall timeline.
Perspectives on the Future of High-Energy Collider Physics
Prof. Karl Jakobs, University of Freiburg / Germany
After the discovery of the Higgs boson at the LHC particle physics has entered a new era. With the successful data taking over the past decade, many properties of this particle have been established. Despite this, important questions remain open and call for experimental exploration. The Higgs field itself is linked to deep structural questions of the Standard Model of particle physics such as flavour, naturalness and the stability of the vacuum. In addition, the nature of the dark matter in the universe and the origin of the matter-antimatter asymmetry remain unknown. Over the past year, within the European Strategy for Particle Physics process, the future of European particle physics has been debated, and recommendations have been expressed for the Future Circular Collider (FCC) as the next large flagship collider project at CERN. In this colloquium, our present understanding of the profile of the Higgs boson and the importance of its further precise exploration are discussed, together with the potential of future colliders in Higgs boson and other areas of physics. The deliberations in the Strategy process and the rationale for the FCC recommendation are summarized.
