The measurement is based on the entire 2011 dataset, corresponding to an integrated luminosity of4.6fb-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 > 30GeV 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.en-USCC BY 4.0 (Attribution)©2014 CERN, for the ATLAS Collaborationhttp://creativecommons.org/licenses/by/4.0/Proton-proton interactionsJets (Nuclear physics)Z bosonsW bosonsMomentum (Physics)TextG.
