Description
The current status of the theoretical and experimental uncertainties associated with the extraction of the strong coupling constant is reviewed, as well as the improvements expected from LHC data in the coming years, and future perspectives achievable in e+e− collisions at the Future Circular Collider (FCC-ee) with O(1--100 ab−1) integrated luminosities yielding 1012 Z bosons and jets, and 108 W bosons and τ leptons, are thoroughly reviewed. The current uncertainty of the 2015 strong coupling world-average value, αs(mZ) = 0.1177 ± 0.0013, is about 1\%. At the FCC-ee, a factor of ten reduction in the αs uncertainty should be possible, mostly from the inclusive measurements from the hadronic decay widths of the Z and W.
