The corresponding integrated luminosity is 650 pb^{-1}. The values of the cross-section obtained are found to be in agreement with QED predictions. Limits on the anomalous magnetic and electric dipole moments of the tau lepton are deduced.20 pages, 9 figures, Accepted by Eur. Phys. J. CHigh Energy Physics - Experimenttext
