The asymptotic approach to the continuum of lattice QCD spectral observables
Nikolai Husung, Peter Marquard, Rainer Sommer
We consider spectral quantities in lattice QCD and determine the asymptotic behavior of their discretization errors. Wilson fermion with O-improvement, (Möbius) Domain wall f…

Challenges for analytic calculations of the massive three-loop form factors
J Blümlein, A. De Freitas, P. Marquard +1
The calculation of massive three-loop QCD form factors using in particular the large moments method has been successfully applied to quarkonic contributions in [1]. We give a brief…

Towards QCD at Five Loops
Andreas Maier, Peter Marquard, York Schröder
We report on recent progress on five-loop calculations in perturbative QCD. We discuss the computation of the perturbative quark condensate, decoupling in QCD, and the precision de…
