TL;DR
This paper derives renormalisation group equations for 2+1 clover fermions and uses them alongside lattice data to analyze scaling behavior across multiple lattice spacings in lattice QCD.
Contribution
It introduces specific renormalisation group equations for 2+1 clover fermions and applies them to study scaling with lattice data.
Findings
Renormalisation group equations for 2+1 clover fermions derived.
Scaling behavior analyzed across five lattice spacings.
Results inform lattice QCD simulations and continuum extrapolations.
Abstract
Many lattice QCD simulations now have many lattice spacings available, and it is of interest to investigate how they scale. In this talk we first derive renormalisation group equations appropriate for 2+1 clover fermions. This is then used together with pion mass and gradient flow results at five lattice spacings to study scaling.
