Measurement of differential Z/gamma*+jet+X cross sections in proton anti-proton collisions at sqrt{s}=1.96 TeV

Understand

We present new measurements of differential cross sections for Z/gamma*(->mumu)+jet+X production in a 1 fb-1 data sample collected with the D0 detector in proton anti-proton collisions at sqrt{s}=1.96 TeV.

• Results include the first measurements differential in the Z/gamma* transverse momentum and rapidity, as well as new measurements differential in the leading jet transverse momentum and rapidity.
• Next-to-leading order perturbative QCD predictions are compared to the measurements, and reasonable agreement is observed, except in the region of low Z/gamma* transverse momentum.
• Predictions from two event generators based on matrix elements and parton showers, and one pure parton shower event generator are also compared to the measurements.
