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 $\alpha_s $. The …

We determine the strong coupling α s from a comprehensive study of energy-energy
correlations (EEC's) and their asymmetry (AEEC's) in hadronic decays of Z 0 bosons …

The present knowledge on the strong coupling is briefly summarized. The most precise
determinations of alpha_s, at different energies, are reviewed and compared at the Z mass …

The strong coupling α s (MZ 2) has been measured using hadronic decays of Z 0 bosons
collected by the SLD experiment at SLAC. The data were compared with QCD predictions …

We present an update of our determination of the strong coupling α s from the quantum
chromodynamics static energy. This updated analysis includes new lattice data, at smaller …

We present two new extractions of the QCD coupling constant at the Z pole, $\alpha_S
(m_Z) $, from detailed comparisons of inclusive W and Z hadronic decays data to state-of …

Theoretical basics and experimental determinations of the coupling parameter of the strong
interaction, α s, are reviewed. The world average value of α s, expressed at the energy scale …

We present the details and first results of a new strategy for the determination of α s (m
Z)(ALPHA Collaboration et al. in Phys. Lett. B 807: 135571, 2020). By simultaneously …

We use a new compilation of the hadronic R-ratio from available data for the process e+ e-→
hadrons to determine the strong coupling, α s. We make use of all data for the R-ratio from …

The value of the strong coupling constant, α _s (M_ Z^ 0), is determined from a study of 15
different observables in hadronic Z 0 and τ decays. The study includes global event shape …
