Description

We present measurements of differential cross sections for the inclusive Z/gamma plus jet production and for the inclusive photon plus heavy flavor production in a data sample of 1fb-1 collected with the D0 detector in proton antiproton collisions at sqrt(s)=1.96TeV. In the first measurement, we compare kinematic distributions of the Z/gamma and the jet as well as of the various angles of the Z+jet system, with different Monte Carlo event generators and next-to-leading order perturbative QCD (NLO pQCD) predictions with non-perturbative corrections applied. In the second measurement, we compare the results with next-to-leading order perturbative predictions, covering photon transverse momenta 30-150 GeV, photon rapidities |y_gamma| < 1.0, jet rapidities |y_jet| < 0.8, and jet transverse momenta pT_jet > 15 GeV.
