Towards lattice-assisted hadron physics calculations based on QCD n-point functions
André Sternbeck, Milena Leutnant, Gernot Eichmann
We present preliminary lattice results for the nonperturbative tensor structure of the vector and axial-vector quark-antiquark vertices in QCD. Our lattice calculations are for $N_…

Quark-photon vertex from lattice QCD in Landau gauge
Milena Leutnant, André Sternbeck
We study the nonperturbative structure of the quark-photon vertex in Landau gauge. To this end, we utilize lattice QCD data for the vector current for two mass-degenerate quark fla…
