We explain a form for the rainbow-ladder kernel whose momentum-dependence is consonant with modern DSE- and lattice-QCD results, and assess its capability as a tool in hadron physics. In every respect tested, this form produces results for observables that are at least equal to the best otherwise obtained in a comparable approach. Moreover, it enables the natural extraction of a monotonic running-coupling and -gluon-mass.

STUDIES OF NUCLEON RESONANCE STRUCTURE IN EXCLUSIVE MESON ELECTROPRODUCTION (2012, background): “Owing to the greater sensitivity of excited states to the long-range part of the interaction in QCD [129, 143, 155], we expect this influence to be even larger in the Q(2)-dependence of nucleon-to-resonance electrocouplings, the extraction of which, via meson electroproduction off protons, is an imp”
Baryons as relativistic three-quark bound states (2016, result): “[359]; with a slight readjustment of parameters the results are essentially the same.”
The QCD running coupling (2016, background): “In recent work [292], the SDE and lattice data are also combined in the form of a massive gluon propagator.”
