Abstract (data abstract)
Fermilab-Tevatron. Measurements of differential cross sections in a variety of variables for the production of isolated prompt photons in antiproton-proton interactions at a centre-of-mass energy of 1.96 TeV. The data sample has an integrated luminosity of 5.36 fb-1 with results presented separately for data having diphoton transverse momentum greater than, and less than, the diphoton invariant mass, as well as the combined sample. Distributions are given in the following variables: The diphoton invariant mass (M) The diphoton transverse momentum (PT) The azimuthal angle difference of the two photons (DPHI) The diphoton rapidity (YRAP) The cosine of the diophoton polar angle (COS(THETA)) The subleading to leading photon transverse momentum ratio.
