Two unavoidable steps to progress in the understanding of matter and its interactions at high energy are the ultra-precise study of the Higgs boson and the full exploration of the 10 TeV (deca-TeV) scale. These objectives are clearly reflected in the conclusions of the 2020 European Strategy for Particle Physics: "An electron-positron Higgs factory is the highest-priority next collider" and "Europe, together with its international partners, should investigate the technical and financial feasibility of a future hadron collider at CERN with a center-of-mass energy of at least 100 TeV and with an electron-positron Higgs and electroweak factory as a possible first stage". A project covering both steps in an optimal way is the Future Circular Collider (FCC) project. It considers an initial electron-positron (FCC-ee) phase in the 90-365 GeV center-of-mass energy range, followed by a hadron-hadron (FCC-hh) phase in the same circular tunnel of about 90 km length, with proton-proton center-of-mass energies approaching 100 TeV. It would be built and operated after the completion of the high-luminosity LHC program. In this seminar we will give an overview of the unique scientific possibilities of the full FCC physics program, with a particular emphasis on the not so well known and surprising richness of the FCC-ee phase.
