Electroweak Precision Physics at the FCC-ee
Abstract
The Future Circular Collider in its electron-positron stage (FCC-ee) will operate as a high-luminosity, multi-purpose collider at the intensity frontier. Its unique combination of centre-of-mass energy reach, absolute beam energy calibration via resonant depolarisation, and huge integrated luminosities will allow for electroweak precision measurements with unprecedented accuracy. The FCC-ee programme includes precise determinations of the $Z$- and $W$-boson properties, measurements of heavy-quark observables, tests of gauge couplings, and sensitivity to physics beyond the Standard Model (BSM) through global fits. This contribution reviews the electroweak prospects at the FCC-ee, focusing on flagship measurements such as the $Z$ lineshape, forward-backward asymmetries, $R_b$, and the $W$ mass, together with recent feasibility studies and detector performance projections.
