摘要：
The electromagnetic form factor of the pi meson is calculated in terms of the QCD sum rules for a pion axial-vector current with allowance made for the radiative QCD corrections. The derived dependence of the pion form factor on the square of the transferred momentum Q(2) is in good agreement with the experimental data. The QCD corrections are shown to make a large contribution, and they should be taken into account in a rigorous theoretical analysis. (c) 2005 Pleiades Publishing, Inc.
