Abstract

We present measurements of differential cross sections in inclusive Z/gamma* plus jet production in a data sample of 1 fb^{-1} collected with the D0 detector in proton antiproton collisions at sqrt{s} = 1.96 TeV. Measured variables include the Z/gamma* transverse momentum and rapidity, the leading jet transverse momentum and rapidity, as well as various angles of the Z+jet system. We compare the results to different Monte Carlo event generators and next-to-leading order perturbative QCD predictions, with non-perturbative corrections applied.
