We present measurements of differential cross sections for the inclusive Z/{gamma}* + jet production and the inclusive photon plus heavy flavor production in a data sample of 1fb{sup -1} collected with the D0 detector in proton-antiproton collisions at {radical}s = 1.96 TeV. In the first measurement, we compare kinematic distributions of the Z/{gamma}* and the jets as well as 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 NLO pQCD predictions, covering photon transverse momenta 30-150 GeV, photon rapidities |y{sup {gamma}}| < 1.0, jet rapidities |y{sup jet}| < 0.8, and jet transverse momenta p{sub T}{sup jet} > 15 GeV.
