AbstractAbstract

[en] We compute Λ_{_MS-bar} for two flavors of light dynamical quarks using non-perturbatively O(a) improved Wilson fermions. We improve on a recent calculation by employing Pade-improved two-loop and three-loop perturbation theory to convert the lattice numbers to the MS-bar scheme
