Higher twist nucleon distribution amplitudes in Wandzura-Wilczek approximation

Abstract

We derive the higher twist (four and five) nucleon distribution amplitudes in the Wandzura-Wilczek approximation. Our method is based on an analysis of the conformal expansion of nonlocal operators in the spinor formalism.
