Log-enhanced discretization errors in integrated correlation functions
Leonardo Chimirri, Nikolai Husung, Rainer Sommer
Integrated time-slice correlation functions with weights appear, e.g., in the moments method to determine from heavy quark correlators, in the muon g-2 determin…

Asymptotic behavior of cutoff effects in Yang-Mills theory and in Wilson's lattice QCD
Nikolai Husung, Peter Marquard, Rainer Sommer
Discretization effects of lattice QCD are described by Symanzik's effective theory when the lattice spacing, , is small. Asymptotic freedom predicts that the leading asymptotic…

Logarithmic corrections to scaling in lattice Yang Mills theory
Nikolai Husung, Peter Marquard, Rainer Sommer
We analyse the leading logarithmic corrections to the scaling of lattice artefacts in QCD, following the seminal work of Balog, Niedermayer and Weisz in the O(n) non-linear s…
