Interaction model for the gap equation
Abstract
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.
