Abstract

We present an overview of the recent lattice determination of the QCD coupling α s by the ALPHA Collaboration. The computation is based on the non-perturbative determination of the Λ-parameter of Nf = 3 QCD, and the perturbative matching of the Nf = 3 and Nf = 5 theories. The final result: α s ( m Z ) = 0.11852 ( 84 ) , reaches sub-percent accuracy.
Keywords: QCD; perturbation theory; lattice QCD QCD; perturbation theory; lattice QCD
