Workshop summary, future prospects and FCC-ee impact on $\alpha_s$

The workshop on “High-precision α s measurements from LHC to FCC-ee” –organized in the con- text of the preparation of the Future Circular Collider (FCC) Conceptual Design Report, within the FCC-e + e − “QCD and photon-photon” physics working group activities– discussed the latest advances in the measurement of the strong interaction coupling α s . The meeting brought together leading experts in the field to explore in depth recent theoretical and experimental developments on the determination of α s , new ways to measure this coupling in lepton-lepton, lepton-hadron and hadron-hadron collisions, and in particular the improvements expected at the proposed Future Circular Collider e + e − (FCC-ee) facility.
