### Description

The future circular collider (FCC) study released a conceptual design report (CDR) in January 2019. FCC-ee can provide $e^+e^−$ collisions with center-of-mass energies of up to 365 GeV and luminosities at the highest energy of 1.4 $10^{34}$ cm$^{-2}$s$^{-1}$ in up to four IPs. Threshold scans enable precision measurements of the top mass and width constraining $\alpha_s$ and $Y_T$, while a run at higher center-of-mass energies allows a precise determination of the top electroweak couplings. These results test the consistency of the SM and push the sensitivity to new physics at high scales.
