Measurement of the inclusive isolated prompt photon cross section in pp collisions at s=1.96 TeV using the CDF detector

A measurement of the cross section for the inclusive production of isolated photons by the CDF experiment at the Fermilab Tevatroncollider is presented. The measurement covers the pseudorapidityregion |{eta}{sup {gamma}}| 30 GeV and is based on 2.5 fb{sup -1} of integrated luminosity. The sample is almost a factor of seven larger than those used for recent published results and extends the E{sub T}{sup {gamma}} coverage by 100 GeV. The result agrees with next-to-leading order perturbative QCDcalculations within uncertainties over the range 50 < E{sub T}{sup {gamma}} < 400 GeV, though the energy spectrum in the data shows a steeper slope at lower E{sub T}{sup {gamma}}.
