We report on a measurement of the cross section for direct-photon production in association with a heavy quark using the full data set of root s = 1.96 TeV proton-antiproton collisions corresponding to 9.1 fb(-1) of integrated luminosity collected by the CDF II detector at the Fermilab Tevatron. The measurements are performed as a function of the photon transverse momentum, covering a photon transverse momentum between 30 and 300 GeV, photon rapidities vertical bar y(gamma)vertical bar < 1.0, a heavy-quark-jet transverse momentum p(T)(jet) > 20 GeV, and jet rapidities vertical bar y(jet)vertical bar < 1.5. The results are compared with several theoretical predictions.

Abstract
We report on a measurement of the cross section for direct-photon production in association with a heavy quark using the full data set of root s = 1.96 TeV proton-antiproton collisions corresponding to 9.1 fb(-1) of integrated luminosity collected by the CDF II detector at the Fermilab Tevatron. The measurements are performed as a function of the photon transverse momentum, covering a photon transverse momentum between 30 and 300 GeV, photon rapidities vertical bar y(gamma)vertical bar < 1.0, a heavy-quark-jet transverse momentum p(T)(jet) > 20 GeV, and jet rapidities vertical bar y(jet)vertical bar < 1.5. The results are compared with several theoretical predictions.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
