Title: Quark distribution amplitudes for the nucleon from perturbative QCD and QCD sum rules

Abstract

We discuss quark distribution amplitudes for the nucleon obtained from perturbative QCD in connection with QCD sum rules on the light cone. Because of nonperturbative contributions these amplitudes have a complex nonsmooth structure and are dominated by strong correlations at the edges of the phase space. The antisymmetric part of the mixed symmetry amplitudes is found to be enhanced.
