Abstract: Measurements are presented of the triple-differential cross section for inclusive isolated-photon+jet events in pppp collisions at ?s=8 TeV as a function of photon transverse momentum (p?T), photon pseudorapidity (??), and jet pseudorapidity (?jet). The data correspond to an integrated luminosity of 19.7fb?1 that probe a broad range of the available phase space, for |??|<1.44 and 1.57<|??|<2.50, |?jet|<2.5, 40
25GeV. The measurements are compared to next-to-leading order perturbative quantum chromodynamics calculations, which reproduce the data within uncertainties.
