Description
Electron-positron interactions producing the final states e+e-e+e-, e+e-μ+μ-, e+e-tau+tau- and μ+μ-μ+μ- have been studied in the CELLO detector at PETRA. Results are presented on 10 events where the four particles emerge at large angle (> 230) with respect to the beam axis. Comparison is made with QED predictions, and an indication is found for an excess of events where all 1+1- masses (1=e,μ,tau) are large. (orig.)
