Title
Study of instanton effects in electromagnetic quark form factor at high energy
Author
Abstract
 The detailed analysis of nonperturbative contributions to the electromagnetic quark form factor is performed within the framework of the instanton liquid model (ILM) of the QCD vacuum. The method of the path-ordered Wilson exponentials is applied to evaluate explicitly the instanton corrections. By using the Gaussian interpolation of the constrained instanton solution, it is shown that the instantons y ield the logarithmic corrections to the amplitudes in high energy limit which are exponentiated in small instanton density parameter.
