A measurement of the ratio of the production cross sections for W and Z bosons in association with jets with the ATLAS detector

    Dataset

    Description

    CERN-LHC.

    The ratio of the production cross sections for W and Z bosons in association with jets has been measured in proton-proton collisions at sqrt(s) = 7 TeV with the ATLAS experiment at the Large Hadron Collider.

    The measurement is based on the entire 2011 dataset, corresponding to an integrated luminosity of 4.6 fb^{-1}. Inclusive and differential cross-section ratios for massive vector bosons decaying to electrons and muons are measured in association with jets with transverse momentum pT > 30 GeV and jet rapidity |y| < 4.4. The measurements are compared to next-to-leading-order perturbative QCD calculations and to predictions from different Monte Carlo generators implementing leading-order matrix elements supplemented by parton showers

    Note added (27 OCT 2015):
    The bin ranges in the DeltaPhi table were incorrectly rounded. This has been fixed.
