Description

Isolated prompt photons provide a direct probe of short­distance physics, complementary to that provided by measurements of jets or vector­bosons. The data are sensitive to the gluon density of the proton. The inclusive prompt photon cross sections have been measured over a wide range of transverse momenta; the diphoton cross section has also been measured as a function of diphoton mass, total transverse momentum and azimuthal separation; the cross section for photons produced in association with jets is also measured. The results are compared to the predictions of next­to­leading­order QCD.
