| Abstract: | 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. |
