| Abstract: | The possibility to constrain the meson distribution amplitude from γ* γ* → π, η, η′ transitions is investigated. It is shown that for a large range in the two photon virtualities the transition form factors are essentially independent of the distribution amplitudes. This in turn entails parameter-free predictions of QCD. |
