Measurement of the triple-differential cross section for photon+jets production in proton-proton collisions at sqrt(s)=7 TeV

Abstract : A measurement of the triple-differential cross section (sigma as a function of the photon pt and eta and the jet eta) 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 inverse femtobarns collected by the CMS detector at the LHC. Photons and jets are reconstructed within a pseudorapidity range of abs(eta) < 2.5, and are required to have transverse momenta in the range 40 < pt(gamma) < 300 GeV and pt(jet) > 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.
