Measurement of the production cross section for W- and Z-bosons in association with jets in ATLAS

We report on the measurements of inclusive W+jets and Z+jets cross sections in proton-proton collisions at sqrt{s} = 7 TeV with the ATLAS detector. Cross sections, in both the electron and muon decay modes of the bosons, are presented as a function of jet multiplicity, the transverse momentum of the...

description We report on the measurements of inclusive W+jets and Z+jets cross sections in proton-proton collisions at sqrt{s} = 7 TeV with the ATLAS detector. Cross sections, in both the electron and muon decay modes of the bosons, are presented as a function of jet multiplicity, the transverse momentum of the jets in the event and the quantity H_T. Measurements are also presented of the ratios of cross sections. The measured cross sections are compared to different particle-level predictions, based on perturbative QCD, where the measured W+3jet cross section is for the first time compared with next-to-leading order calculations.

Cross sections, in both the electron and muon decay modes of the bosons, are presented as a function of jet multiplicity, the transverse momentum of the jets and the quantity HT which is the scalar sum of the pT in the event.
