Title: Measurement of the triple-differential cross section for photon+jets production in proton-proton collisions at √s = 7 TeV

Abstract

A measurement of the triple-differential cross section, $$ {{{{{\mathrm{d}}^3}\sigma }} \left/ {{\left( {\mathrm{d}\mathrm{p}_T^{\gamma}\mathrm{d}{\eta^{\gamma }}\mathrm{d}{\eta^{\mathrm{jet}}}} \right)}} \right.} $$ , 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 |η| < 2.5, and are required to have transverse momenta in the range 40 < $$ p_{\mathrm{T}}^{\mathrm{jet}} $$ < 300 GeV and $$ p_{\mathrm{T}}^{\mathrm{jet}} $$ > 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. Lastly, the predictions are found to be consistent with the data over most of the examined kinematic region.
