Description
This document provides a comprehensive summary of the state-of-the-art, challenges, and prospects in the experimental and theoretical study of the strong coupling . The current status of the seven methods presently used to determine based on:(i) lattice QCD,(ii) hadronic decays,(iii) deep-inelastic scattering and parton distribution functions fits,(iv) electroweak boson decays, hadronic final-states in (v) e+ e-,(vi) ep, and (vii) pp collisions, and (viii) quarkonia decays and masses, are reviewed. Novel determinations are discussed, as well as the averaging method used to obtain the PDG world-average value at the reference Z boson mass scale, . Each of the extraction methods proposed provides a" wish list" of experimental and theoretical developments required in order to achieve an ideal permille precision on within the next 10 years.
