The strange quark mass and Lambda parameter of two flavor QCD

Understand

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.
