Title: FCC-ee the first step in a long term vision for particle physics

Abstract: CERN is undertaking an integral design study of Future Circular Colliders of a circumference of 100km around Geneva. A possible first step is a high luminosity electron-positron (lepton) collider covering the energy range from the Z pole to above the top threshold, for the study of several TeraZ, okuW, MegaHiggs and Megatops. The ultimate goal is a 100 TeV pp collider. The project will be described with special attention to the electron machine.

The combination of the two machines offers a remarkable potential for discoveries, from a blend of precision measurements, high statistics, high energies and sensitivity to very small couplings. In particular the search for sterile right-handed neutrinos (aka neutral heavy leptons) will be shown to reach all the way up to the Z mass, in a way complementary to the SHIP experiment.
