Measurement of the inclusive-isolated prompt-photon cross section in pp¯ collisions using the full CDF data set

A measurement of the inclusive production cross section of isolated prompt photons in proton-antiproton collisions at center-of-mass energy $\sqrt{s}=1.96\text{ }\text{ }\mathrm{TeV}$ is presented. The results are obtained using the full Run II data sample collected with the Collider Detector at the Fermilab Tevatron, which corresponds to an integrated luminosity of $9.5\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$. The cross section is measured as a function of photon transverse energy, ${E}_{T}^{\ensuremath{\gamma}}$, in the range $30l{E}_{T}^{\ensuremath{\gamma}}l500\text{ }\text{ }\mathrm{GeV}$ and in the pseudorapidity region $|{\ensuremath{\eta}}^{\ensuremath{\gamma}}|l1.0$. The results are compared with predictions from parton-shower Monte Carlo models at leading order in QCD and from next-to-leading-order perturbative QCD calculations. The latter show good agreement with the measured cross section.
