QCD Coupling from a Nonperturbative Determination of the Three-Flavor ?? Parameter
(2017)We present a lattice determination of the Λ parameter in three-flavor QCD and the strong coupling at the Z pole mass. Computing the nonperturbative running of the coupling in the range from 0.2 to 70 GeV, and using ...
