Nucleon to Pion Transition Distribution Amplitudes in a Light-Cone Quark Model

Abstract

We present a general representation for the nucleon distribution amplitudes and for the nucleon to pion transition distribution amplitudes in terms of light-cone wave functions. We apply our formalism to a light-cone constituent quark model giving some numerical results for both the classes of observables.
