Abstract (summary)

In a sample of 200000 Z decays, events with two leptons and an additional pair of opposite charged particles are studied. The 35 events found show a possible excess in the tau channel compared with the expectation from electroweak processes. Other features of the events are studied and are not found to be in contradiction to the electroweak prediction for the radiation of virtual photons.
