Measurement of the Cross Section for Production of Two Isolated Prompt Photons at CDF 2

The diphoton differential cross section as function of the invariant mass from CDF Run 2 data, along with predictions from DIPHOX (solid), ResBos(dashed), and PYTHIA (dot-dashed). The PYTHIA predictions have been scaled up by a factor of 2. The inset shows, on a linear scale, the total NLO cross section from DIPHOX with(solid)/without(dashed) the gluon-gluon contribution.

The differential cross section as function of diphoton system pT (referred as "qT") from CDF Run 2 data, along with predictions from DIPHOX (solid), ResBos(dashed), and PYTHIA(dot-dashed). The PYTHIA predictions have been scaled up by a factor of 2. Also shown, at larger qT, are the DIPHOX prediction (dot) and the CDF Run 2 data (open squares) for the configuration where the two photons are required to have delta_phi < pi/2.

The differential cross section as function of delta_phi between the two photons from CDF Run 2 data, along with predictions from DIPHOX(solid), ResBos(dashed), and PYTHIA (dot-dashed). The PYTHIA predictions have been scaled up by a factor of 2.
