Title: Nucleon quark distribution functions from the Dyson–Schwinger equations

Abstract

Here, we present results for the nucleon's leading-twist spin-independent valence parton distribution functions obtained from a theoretical framework based on the Dyson–Schwinger equations (DSEs) of QCD that previously gave an excellent description of nucleon electromagnetic form factors. Key dynamical elements selected by experience with the rainbow-ladder truncation of the DSEs are implemented. We utilize nucleon bound state amplitudes from the Poincaré-covariant Faddeev equation that implements the dominant scalar and axial-vector quark–quark correlations.
