Description

Relating the value of the strong coupling at the electroweak scale with the experimental value of hadronic quantities is a theoretical challenge that requires a non-perturbative formulation of the strong interactions. Lattice QCD provides an adequate theoretical framework to attack this problem. Our collaboration has developed a systematic strategy to connect non-perturbatively the low energy region of QCD with its high energy perturbative domain. After many years of applications to the pure gauge theory and two-flavour theory, we have applied this strategy to the three flavour theory. This study allow us to determine $\alpha_s(M_Z)$ in a controlled and precise fashion.
