Summary: The production of direct photons in association with jets can be used to probe gluon parton distribution functions as well as to test perturbative Quantum Chromodynamics. This thesis presents the measurement of the triple differential cross section for photon plus jet evehts as a function of photon transverse momentum (pTgamma), photon pseudorapidity (etagamma), and jet pseudorapidity (etajet). The measurement is made using 19.7 fb-1 of data collected by the Compact Muon Solenoid detector in proton-proton collisions at the center-of-mass energy of 8 TeV. The kinematic regions probed are 40 < pTgamma < 1000 GeV, |eta gamma| < 2.5 and |etajet| < 2.5. These results are compared to next-to-leading order theoretical predictions.
