No-scale supergravity confronts LEP diphoton events

We note that two acoplanar diphoton events observed at LEP, by OPAL at sqrt{s}=130 GeV and by L3 and sqrt{s}=161 GeV, are consistent with the predictions of our previously proposed one-parameter no-scale supergravity model with a light gravitino, via the process e^+e^- -> chi chi -> gamma gamm...
