Measurement of the cross section for prompt isolated diphoton production in pp collisions at square root(s) = 1.96  TeV.

This Letter reports a measurement of the cross section of prompt isolated photon pair production in pp collisions at a total energy square root(s)=1.96  TeV using data of 5.36  fb(-1) integrated luminosity collected with the CDF II detector at the Fermilab Tevatron. The measured cross section, diffe...

description This Letter reports a measurement of the cross section of prompt isolated photon pair production in pp collisions at a total energy square root(s)=1.96  TeV using data of 5.36  fb(-1) integrated luminosity collected with the CDF II detector at the Fermilab Tevatron. The measured cross section, differential in basic kinematic variables, is compared with three perturbative QCD predictions, a leading order parton shower calculation and two next-to-leading order calculations. The next-to-leading order calculations reproduce most aspects of the data. By including photon radiation from quarks before and after hard scattering, the parton shower prediction becomes competitive with the next-to-leading order predictions.
