Scale setting and the light baryon spectrum in $N_f=2+1$ QCD with Wilson fermions

Understand

We determine the light baryon spectrum on ensembles generated by the Coordinated Lattice Simulations (CLS) effort, employing $N_f=2+1$ flavours of non-perturbatively improved Wilson fermions.

• The hadron masses are interpolated and extrapolated within the quark mass plane, utilizing three distinct trajectories, two of which intersect close to the physical quark mass point and the third one approaching the SU(3) chiral limit.
• The results are extrapolated to the continuum limit, utilizing six different lattice spacings ranging from $a\approx 0.10\,$fm down to below $0.04\,$fm.
• The light pion mass varies from $M_{\pi}\approx 429\,$MeV down to $127\,$MeV.
