Abstract
The holographic QCD prediction for the pion distribution amplitude (DA) is used to compute the pion spacelike electromagnetic form factor within the QCD light-cone sum rule method. In calculations the pion's renormalon-based model twist-4 DA, as well as the asymptotic twist-4 DA are employed. Obtained theoretical predictions are compared with experimental data and with results of the holographic QCD.
