Résumé :

Tau-pair production in the process e+e- → e +e T+T- was studied using data collected by the DELPHI experiment at LEP2 during the years 1997 - 2000. 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. © Springer-Verlag / Società Italiana di Fisica 2004.
