Pion distribution amplitude from holographic QCD and the electromagnetic form factor F_pi(Q2)

Abstract

The holographic QCD prediction for the pion distribution amplitude (DA) ${\varphi }_{hol}(u)$ is used to compute the pion spacelike electromagnetic form factor $F_{\pi }(Q^2)$ 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.
