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.

  1. Precision renormalisation and improvement of $N_{\rm f}=3$ lattice QCD with Wilson fermions

    hep-lat 2026-06 unverdicted novelty 6.0

    New non-perturbative renormalization and improvement results for currents and masses in Nf=3 O(a)-improved Wilson QCD at small a using Schrödinger functional boundary conditions and gradient flow tuning.

  2. Variance reduction strategies for lattice QCD

    hep-lat 2026-05 unverdicted novelty 2.0

    Variance reduction schemes based on decompositions of quark propagators have proven useful for precision lattice QCD observables and may help reduce the computational cost of reaching large volumes.
