Abstract
We present a measurement of the triple-differential cross section in photon+jets final states using a data sample from proton-proton collisions at 7 TeV. This sample corresponds to an integrated luminosity of 2.14 fb^−1 collected by the Compact Muon Solenoid (CMS) detector at the Large Hadron Collider (LHC). Photons and jets are reconstructed within a pseudorapidity range of |η| < 2.5, and are required to have transverse momentum in the range 40 < p_γ < 300 GeV and p_jet > 30 GeV, respectively. The measurements are compared to theoretical predictions from the sherpa leading-order 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 much of the examined kinematic region.
