Description

We discuss the status of the pion distribution amplitude (DA) in connection with QCD sum rules and experimental data on the γ*γ* → π0 transition form factor. Contents: (a) Pion DA in generalized QCD Sum Rules (SRs); (b) Light Cone Sum Rules (LCSR) analysis of the CLEO data for the γ*γ → π0 transition form factor; (c) Recent lattice QCD data for the pion DA; (d) BaBar data - a challenge for QCD?
