Abstract | The results of studies on the ef.7-y events with high 'Y'Y mass from the L3 experiment at LEP is reported. A clustering of events with 'Y'Y invariant mass around 60 GeV is observed. The clustering could come from decay of a heavy particle, however, QED fluctuation cannot be ruled out. More data are needed to ascertain the origin of these events. |
