Sažetak
We comment on the results of a complete leading-twist next-to-leading order QCD analysis of the spacelike pion electromagnetic form factor at large-momentum transfer Q. For the asymptotic distribution amplitude, we have examined the sensitivity of the predictions to the choice of the renormalization scale. The results show that, regarding the size of the radiative corrections, reliable perturbative predictions for the pion electromagnetic form factor can already be made at a momentum transfer Q of the order of 5 to 10 GeV.
