摘要
We describe the present status of the pion distribution amplitude as it originated from two sources: (i) a nonperturbative approach, based on QCD sum rules with nonlocal condensates and (ii) a NLO QCD analysis of the CLEO data on F^{\gamma\gamma^*\pi}(Q^2), supplemented by the recent high-precision lattice calculations of the second moment of the pion distribution amplitude.
