Abstract:

Some basics issues of the electromagnetic radiative corrections to collisions at DANE energies are reviewed in the framework of the QED structure function approach. Illustrative numerical results for the line--shape and leptonic pair production over a realistic experimental set--up are given. A phenomenological analysis of radiative Bhabha scattering, with particular emphasis on the very forward region, is also addressed. Predictions for the tagging configurations of interest for the two--photon physics at DANE are given and compared with previous and very recent calculations.
