Abstract： The Future Circular Collider (FCC) with its electron-positron collision phase (FCC-ee) will serve as a perfect Higgs factory and provide unprecedented precision on the fundamental properties of the Higgs boson. At the center-of-mass energies 240 and 365 GeV, the FCC-ee will produce millions of Higgs bosons via Higgs-strahlung and vector boson fusion. The clean experimental environment allows a model-independent measurement of the absolute ZH cross-section to better than per-mil accuracy, directly determining the Higgs coupling to Z bosons. Utilizing the recoil-mass technique in leptonic and hadronic Z decays, the Higgs boson mass will be measured with a precision of a few MeV. The Higgs branching ratios to almost all channels can be measured exclusively and model-independently with high precision. In particular, FCC-ee will measure the Higgs branching ratios to b, c, and gluon jets with sub-percent to few-percent accuracy. The combination of these measurements will provide an unprecedented knowledge of the Higgs physics landscape and guide the search for new physics.
