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 = 3 QCD, and the perturbative matching of the = 3 and = 5 theories. The final result: α s ( m Z ) = 0 . 11852 ( 84 ) , reaches sub-percent accuracy.
