Abstract We have studied the processpp→γγ+X at $$\sqrt s = 63 GeV$$ GeV in the central rapidity region. We report a positive signal at 96% C.L., a ratio γγ/e + e −=4.0±3.0 when the transverse momentum of each photon is above 2 GeV/c, and a cross-sectiondσ/dydM γγ=(5.5±2.7)×10−34 cm2/GeV when |y|〈0.5,4〈M γγ〈6 GeV.
