Measurement of the triple-differential cross section for photon+jets production in proton-proton collisions at $\sqrt{s}$ = 7 TeV
J. High Energy Phys. 06 (2014) 009
Abstract: A measurement of the triple-differential cross section, $ \mathrm{d}^3 \sigma / ( \mathrm{d} p^{\gamma}_{\mathrm{T}} \mathrm{d}\eta^{\gamma} \mathrm{d} \eta^{\text{jet}})$, in photon + jets final states using a data sample from proton-proton collisions at $ \sqrt{s} $ = 7 TeV is presented. This sample corresponds to an integrated luminosity of 2.14 fb$^{-1}$ collected by the CMS detector at the LHC. Photons and jets are reconstructed within a pseudorapidity range of $ | \eta | <$ 2.5, and are required to have transverse momenta in the range 40 $< p^{\text{jet}}_{\mathrm{T}} <$ 300 GeV and $ p^{\text{jet}}_{\mathrm{T}} >$ 30 GeV, respectively. The measurements are compared to theoretical predictions from the sherpa leading-order QCD Monte Carlo event generator and the next-to-leading-order perturbative QCD calculation from jetphox. The predictions are found to be consistent with the data over most of the examined kinematic region.
