| Abstract |
We report a measurement of the production cross section of prompt isolated photon
pairs in proton-antiproton collisions at a total CM energy of 1.96 TeV using 5.36
fb-1 of data collected with the CDF IIb detector at the Fermilab Tevatron
collider. The cross section is presented as a function of kinematic variables
sensitive to the reaction mechanism. The data are compared with three pertinent
model calculations, at leading order, fixed next-to-leading order, and PT-resummed
matched to next-to-leading order in the strong coupling at the hard scattering. The
comparison shows that none of the models adequately describes all aspects of the data.
