FCC is a project for a next generation circular collider based at CERN, as the next step of LEP/LHC experiments. It will have at least two stages : (i) measurements on electroweak (Z/W), Higgs, tt by e+e− collision (FCC-ee) and (ii) energy frontier pp collision (FCC-hh) up to 100 TeV center of mass (CM) energy. Both will be performed by colliders in the same tunnel with 90–100 km circumference built around the Geneva area across the Swiss-French border.
