摘要：

We present measurements from events with two isolated prompt photons in ppBAR collisions at square-root s=1.8 TeV. The differential cross section, measured as a function of transverse momentum (P(T)) of each photon, is about 3 times what next-to-leading-order QCD calculations predict. The cross section for photons with P(T) in the range 10-19 GeV is 86 +/- 27(stat)-23(+32)(syst) pb. We also study the correlation between the two photons in both azimuthal angle and P(T). The magnitude of the vector sum of the transverse momenta of both photons, K(T)=\P(T1) + P(T2)\, has a mean value of [K(T)]=5.1 +/- 1.1 GeV.
