Description
The Future Circular Collider stands at the forefront of the European Strategy for Particle Physics vision. A technical and financial feasibility study for the 100 km infrastructure is currently underway. A main objective of the FCC is to comprehensively explore the properties of the Higgs boson in e+e- collisions. The FCC-ee makes use of the well-known centre-of-mass energy by using Z tagging to perform a model-independent determination of the ZH cross-section at 240 GeV. This will allow for a measurement of the coupling to Z bosons and, in turn, the total width. In combination with branching ratio measurements, the absolute couplings to W, b, c, g (and, likely, strange) will be known at the FCC-ee. The measurements of top quark properties at FCC-ee will be instrumental in the measurement of the top Yukawa coupling. A combination of the measured cross sections at the two different centre-of-mass energies (240 and 365 GeV) further provides the first evidence for the trilinear Higgs self-coupling. Finally, the FCC-ee offers a unique opportunity to determine the electron Yukawa coupling by searching for the s-channel Higgs production at sqrt(s) = 125 GeV. The detailed detector requirements imposed by such important measurements will be reviewed.
