The process pˉp -> photon + jet + X as studied by the D0 detector at the Fermilab Tevatron collider at center-of-mass energy s=1.96TeV. Photons are reconstructed in the central rapidity region |yγ|<1.0 with transverse momenta in the range 30--400 GeV, while jets are reconstructed in either the central |yjet|<0.8 or forward 1.5<|yjet|<2.5 rapidity intervals with pjet>15GeV. The differential cross section d3σ/dpγdyγdyjet is measured as a function of pγ in four regions, differing by the relative orientations of the photon and the jet. MC predictions have trouble with simultaneously describing the measured normalization and pγ dependence of the cross section in any of the four measured regions.
