Abstract

The proposed high-luminosity, circular electron-positron collider, FCC-ee, provides unparalleled opportunities for precise exploration of Higgs, electroweak, top, flavour, and beyond standard model physics. Very advanced detector systems are required to fully exploit this diverse physics programme. Key requirements include excellent resolutions on the measurement of momentum, energy, and impact parameters; exquisite particle identification capabilities over a wide momentum range including photon/{\pi}0 separation; sensitivity to far-displaced vertices in the tracking (and possibly also the calorimeter) volume; and very precise absolute and relative normalisation. This note presents an overview of detector requirements and the status of detector design efforts
