/ Abstract
Abstract The scale parameter Λ MS is computed on the lattice in the quenched approximation and for Nf=2 flavors of light dynamical quarks. The dynamical calculation is done with non-perturbatively O(a) improved Wilson fermions. In the continuum limit we obtain Λ MS N f =0 =243(1)(10) MeV and Λ MS N f =2 =217(16)(11) MeV, respectively.
