High-Q2 elastic ed scattering and QCD predictions.

In the framework of perturbative QCD it is argued that in the elastic [ital ed] scattering at [ital Q][sup 2][similar to] few (GeV/c)[sup 2] the light-cone-frame helicity-flip amplitudes could not be omitted. The obtained [ital B]/[ital A] ratio of Rosenbluth structure functions is shown to be in a good agreement with experimental data. The high-[ital Q][sup 2] behavior of [ital T][sub 20] is discussed.
