The principles of scale setting in lattice QCD as well as the advantages and disadvantages of various commonly used scales are discussed. After listing criteria for good scales, I concentrate on the main presently used ones with an emphasis on scales derived from the Yang-Mills gradient flow. For these I discuss discretisation errors, statistical precision and mass effects. A short review on numerical results also brings me to an unpleasant disagreement which remains to be explained.

Discussion (0). Continue with ORCID to comment.

  1. Lattice study of spin interactions between heavy quarks in the quark-gluon plasma

    hep-lat 2026-07 conditional novelty 8.0 of 10

    The spin-dependent heavy-quark potential in the quark-gluon plasma is complex, with a channel-dependent imaginary part first extracted from lattice QCD.

  2. Lattice QCD Study of Anomalous Transport Phenomena in Strongly Interacting Matter

    hep-lat 2025-09 conditional novelty 8.0 of 10

    First physical-point lattice QCD calculation of the Chiral Separation Effect conductivity, a zero equilibrium Chiral Magnetic Effect with conserved currents, and a localized equilibrium CME in inhomogeneous fields.

  3. Staggered fermions with taste splitting mass term on dynamical configurations

    hep-lat 2026-07 conditional novelty 5.0 of 10

    Preliminary Nf=2 dynamical simulations of single-taste staggered fermions find negligible rotational-symmetry counterterms and a computable but still-too-heavy pion mass on volumes up to 16^4.

  4. The order of the chiral phase transition in massless many-flavour lattice QCD

    hep-lat 2025-01 conditional novelty 5.0 of 10

    Lattice QCD simulations with up to seven flavors indicate that the first-order chiral transition seen on coarse lattices is a cutoff artifact, so the continuum chiral transition is second-order for all flavors up to t...
