Abstract :
[en] The pion-photon Transition Distribution Amplitudes (TDAs) are studied, treating the pion as a bound state in the Bethe-Salpeter sense, in the formalism of the NJL model. The results obtained explicitly verify support, sum rules and polynomiality conditions. The role of PCAC is highlighted. © 2008 Elsevier B.V. All rights reserved.
