Low-energy amplitudes in the non-local chiral quark model

High Energy Physics - Phenomenology 2010-02-19 v2

Abstract

We apply chiral quark model with momentum dependent quark mass to two kinds of non-perturbative objects. These are: photon Distribution Amplitudes which we calculate up to twist-4 in tensor, vector and axial channels and pion-photon Transition Distribution Amplitudes together with related form factors. Where possible we compare our results with experimental data.
