QED radiative corrections to impact factors

We consider the radiative corrections to the impact factors of electron and photon. According to a generalized eikonal representation the e + e − scattering amplitude at high energies and fixed momentum transfers is proportional to the electron formfactor. But we show that this representation is violated due to the presence of non-planar diagrams. One loop correction to the photon impact factor for small virtualities of the exchanged photon is obtained using the known results for the cross section of the e + e − production at photon nuclei interactions.
