摘要: 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 proton anti-proton collisions at sqrt{s}=1.96 TeV. Results include first Z/gamma* transverse momentum and rapidity, as well leading jet rapidity. Next-to-leading order perturbative QCD predictions are compared to measurements, reasonable agreement is observed, except region low momentum. Predictions from two event generators based on matrix elements parton showers, one pure shower generator also measurements. These show significant overall normalization differences have varied success describing shape distributions.
