talkabstract = "We study the pion structure in terms of the pion Distribution Amplitude (DA) and the transition pion-photon form factor in frameworks of QCD sum rules with nonlocal condensate and light-cone sum rules. A global fit of pion DA to the data from different collaborations (CELLO, CLEO, BaBar, Belle) on the pion-photon transition form factor is carried out using light-cone sum rules. The analysis includes the next-to-leading QCD radiative corrections and the twist-four contributions, while the main next-to-next-to-leading term and the twist-six contribution are taken into account in the form of theoretical uncertainties."
