 Title: Study of the associated production of photons and b-quark jets in pp̅ collisions at √s=1.96  TeV Alternative title: A study of the associated production of photons and b-quark jets in p-pbar collisions at sqrt{s} = 1.96 TeV Author: Aaltonen, T; Mehtala, P.; Orava, R.; Saarikko, H.; Osterberg, K.; CDF Collaboration Contributor organization: Department of PhysicsHelsinki Institute of Physics Date: 2010 Language: eng Number of pages: 8 Belongs to series: Physical Review D : Particles, Fields, Gravitation and Cosmology ISSN: 1550-7998 DOI: https://doi.org/10.1103/PhysRevD.81.052006 URI: http://hdl.handle.net/10138/24476 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 $E_T^{\gamma}$, $d \sigma$($p \overline{p} \to \gamma + \geq 1 b$-jet)/$d E_T^{\gamma}$ and the total cross section $\sigma$($p \overline{p} \to \gamma + \geq 1 b$-jet; $E_T^{\gamma}> 20$ GeV) are measured. Comparisons to a next-to-leading order prediction of the process are presented.The cross section for photon production in association with at least one jet containing a b quark has been measured in proton antiproton collisions at √s=1.96  TeV. The data sample used corresponds 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 ETγ and the total cross section are measured and compared to a next-to-leading order prediction for the process.
