Lepton pair production by two-photon processes has been studied using the JADE detector at PETRA. The study probed QED to α4 in the highestQ 2 region. Both electrons and positrons were tagged by the endcap or barrel shower counters. The observed events consist of two produced leptons as well as two tagged electrons. These events show good agreement with QED to order α4.
