摘要：We determine fK for lattice QCD in the two flavor approximation with non-perturbatively improved Wilson fermions. The result is used to set the scale for dimensionful quantities in CLS/ALPHA simulations. To control its dependence on the light quark mass, two different strategies for the chiral extrapolation are applied. Combining fK and the bare strange quark mass with non-perturbative renormalization factors and step scaling functions computed in the Schrödinger Functional, we determine the RGI strange quark mass and the Lambda parameter in units of fK.
