Structure function approach in QED for high energy processes

In this review we consider the structure function method, based on the renormalization group approach: when combined with exact calculation at the lowest order of perturbation theory it allows one to calculate the differential cross sections in leading and next to leading order approximations, again...

Description
Summary:In this review we consider the structure function method, based on the renormalization group approach: when combined with exact calculation at the lowest order of perturbation theory it allows one to calculate the differential cross sections in leading and next to leading order approximations, again providing the thousands accuracy. The implementation of this method to calculation of radiative corrections is also done for some processes on colliders. Among them radiative corrections to DVCS tensor, π e 2 decay, Deep Inelasic Scattering, muon decay, Bhabha scattering, electron-positron annihilation and others. In some cases the explicit expression of non-leading terms (so called K-factor) is given or numerical estimation of it is done.
