Short-flow-time expansion of non-singlet twist-two operators at next-to-next-to-leading order QCD
Robert V. Harlander, Jonas T. Kohnen, Andrea Shindler
The gradient-flow formalism provides a framework for the direct determination of moments of parton distribution functions (PDFs) from lattice QCD calculations. Their conversion fro…

Gradient flow for parton distribution functions: first application to the pion
Anthony Francis, Patrick Fritzsch, Robert V. Harlander +9
Parton distribution functions (PDFs) are central to precision QCD phenomenology. Their Mellin moments can be computed on the lattice, but direct determinations using local operator…

Two-loop gradient-flow renormalization of scalar QCD
J. Borgulat, N. Felten, R. V. Harlander +1
The gradient-flow formalism is applied to a non-Abelian gauge theory with scalar and fermionic particles, dubbed "scalar QCD". It is shown that the flowed scalar quark requires a f…
