AbstractAbstract
[en] A search for massive photon pair production at √s = 63 GeV has been carried out on the data sample previously employed for the electron pair production study. Positive evidence is reported for mγγ > 6 GeV, with a production cross-section similar to Drell-Yan electron pairs. The ratio γγ/π0π0 was measured to be approx. 10-3 for a pT of each γ or π0 above 3 GeV/c
