Mapping out the quark structure of hadrons in QCD
Abstract
In the context of QCD sum rules with non-local condensates we present a pion distribution amplitude, which is double-humped with its end-points x(0,1) strongly suppressed, and show that it matches the CLEO experimental data on the pion-photon transition at the 1σ level accuracy, being also in compliance with the CELLO data. We also include some comments on the nucleon distribution amplitude and the nucleon evolution equation.
