In 2018, the global Future Circular Collider (FCC) study has completed the conceptual design of a far-reaching post-LHC accelerator infrastructure at CERN, with a circumference 3-4 times the LHC’s. The resulting “FCC integrated program” consists, in a first stage, of an energy- and luminosity-frontier electron-positron collider, FCC-ee. The FCC-ee is a precision instrument to study the Z, W, and Higgs boson, and the top quark, and offers unprecedented sensitivity to signs of new physics. Most of the FCC-ee infrastructure can be reused for the subsequent hadron collider, FCC-hh, which provides proton-proton collisions at a centre-of-mass energy of 100 TeV and can directly produce new particles with masses of up to several tens of TeV. This collider also measures the Higgs self-coupling and explores the dynamics of electroweak symmetry breaking. Construction of the FCC-hh requires novel high-field magnets, which are being developed with several international partners. In this Colloquium, I will present selected highlights and key challenges from the FCC design, including physics prospects, near-term study targets, and the longer-term FCC schedule.
