A study of the associated production of photons and b-quark jets in p-pbar collisions at sqrt{s} = 1.96 TeV

Abstract

The cross section for photon production in association with at least one jet containing a $b$-quark hadron has been measured in proton antiproton collisions at $\sqrt{s}=1.96$ TeV. The analysis uses a data sample corresponding to an integrated luminosity of 340 pb${}^{-1}$ collected with the CDF II detector. Both the differential cross section as a function of photon transverse energy $E_T^{\gamma }$, $d\sigma$($p\overline{p}\to \gamma +\ge 1b$-jet)/$d{E}_T^{\gamma }$ and the total cross section $\sigma$($p\overline{p}\to \gamma +\ge 1b$-jet; $E_T^{\gamma }>20$ GeV) are measured. Comparisons to a next-to-leading order prediction of the process are presented.
