Анотація: The possibility of a precise scanning of the hadron crosssection in the process of electron-positron annihilation is considered. It can be done by selection and analysis of the events with collinear photons and an esup+/sup esup-/sup-pair radiated from the initial state. The energy distribution for all particles, hitting a detector placed along the electron beam direction, is derived taking into account radiative corrections. The corresponding contribution due to photon emission is calculated with next-next-to-leading order (NNLO) accuracy, and the contribution caused by the pair production with next-to-leading order (NLO) one. The results obtained are illustrated with numerical estimations. !oprip481_H.pft: FILE NOT FOUND!
