The "alphas-2025: Workshop on precision measurements of the strong coupling constant" will be held at the CNRS Paul Langevin Center in Aussois (Savoie) in the third week of December 2025: Mon. 15th to Friday 19th (in-person participants should expect to arrive on Sun. 14th afternoon, dinner will be served. The workshop will end at noon on Friday 19th, lunch will be served).
The workshop aims at exploring in depth the current status and upcoming prospects in the determination of the QCD coupling constant $\alpha_S(m_Z)$ from the key observables where high-precision experimental measurements and theoretical calculations are (or will be) available: (i) lattice QCD, (ii) hadronic decays of tau leptons, (iii) deep-inelastic electron-proton scattering and global parton densities analyses, (iv) QCD corrections to electroweak precision observables, and analysis of (v) hadronic final states in high energy particle collisions ($e^+e^-$, ep, and pp).
