摘要:
Monte-Carlo generator with photon jets radiation in collinear regions for the process e(+)e(-) --> gamma gamma is described in detail. Radiative corrections in the first order of a are treated exactly. Large leading logarithmic corrections coming from collinear regions are taken into account in all orders of a by applying the Structure Function approach. Theoretical precision of the cross section with radiative corrections is estimated to be 0.2%. This process is considered as an additional tool to measure luminosity in forthcoming experiments with the CMD-3 detector at the e(+)e(-) collider VEPP-2000.
