A measurement of the triple-differential cross section, , in photon + jets final states using a data sample from proton-proton collisions at = 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| LT 2.5, and are required to have transverse momenta in the range 40 LT LT 300 GeV and GT 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.
