Description
The parton structure of the nucleon is investigated using QCD's Dyson-Schwinger equations (DSEs). The formalism used here builds in numerous features of a QCD approach, for example, the dressing of parton propagators and dynamical formation of non-pointlike di-quark correlations. All needed elements, including the nucleon wave function solution from a Poincar\'e covariant Faddeev equation, are encoded in spectral-type representations in the Nakanishi style. This greatly facilitates calculations and allows insight into how the essential features of the parton distributions arise from key underlying mechanisms. As a first step, results for the nucleon quark distribution functions will be presented. A major aim is the extension to the transverse momentum-dependent parton distributions (TMDs) and initial results for this will be discussed if possible.
