Asymptotic behavior of cutoff effects in Yang–Mills theory and in Wilson's lattice QCD

N Husung, P Marquard, R Sommer - The European Physical Journal C, 2020 - Springer
Discretization effects of lattice QCD are described by Symanzik's effective theory when the
lattice spacing, a, is small. Asymptotic freedom predicts that the leading asymptotic behavior …
