Higgs measurements at the Future Circular Colliders

Precision measurements and searches for new phenomena in the Higgs sector are amongst the most important goals in particle physics. Experiments at the Future Circular Colliders (FCC) are ideal to study these questions. Electron-positron collisions (FCC-ee) up to an energy of 365 GeV will allow to measure with a great precision the Higgs boson couplings, mass, total width, but also to search for exotic and invisible Higgs boson decays. Very high energy proton-proton collisions (up to 100 TeV) provided by the subsequent FCC-hh will allow a measurement of the Higgs boson self-coupling. There is a remarkable complementarity of the FCC-ee and FCC-hh colliders, which in combination offer the best possible overall study of the Higgs boson properties.
