Description
The proposed ultra-high luminosity, circular electron-positron colliders,
FCC-ee and CEPC, feature a very rich and diverse physics programme including
i) precise measurements of Higgs boson couplings;
ii) a ultra-precise electroweak programme promising indirect sensitivity to
New Physics up to the 70-TeV scale;
iii) a next-generation heavy-flavour programme with statistics exceeding that
of Belle II by more than one order of magnitude;
and iv) direct searches for feebly Beyond-Standard-Model particles over a wide
parameter space.
Very advanced detector designs are required to fully exploit this diverse
physcis 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 foton/pi0
separation; sensitivity to far-displaced vertices in the tracking (and
possibly the calorimeter) volume; and very precise asolute and relative
normalisation. The talk will pressent an overview of the detector requirements
and of the status of the detector design efforts.
