摘要：

We complete the non-perturbative calculations of the strange quark mass and the Lambda parameter in two flavor QCD by the ALPHA Collaboration. The missing lattice scale is determined via the kaon decay constant, for whose chiral extrapolation complementary strategies are compared. We also give a value for the scale r(0) in physical units as well as an improved determination of the renormalization constant Z(A). (c) 2012 Elsevier B.V. All rights reserved.
