Discussing the light-meson DAs

The light-cone distribution amplitudes of the pseudoscalar and scalar light mesons are (re)analyzed in the pure perturbative QCD approach to the meson transition form factors, as well as, in the combined analysis of several hard exclusive processes. The informations obtained from the confrontation with the experimental data, the open questions and the limitations of the approach will be discussed.
