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 p(T) > 30 GeV and jet rapidity vertical bar y vertical bar < 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. %R 10.1140/epjc/s10052-014-3168-9 %U http://arxiv.org/abs/1408.6510 %U https://doi.org/10.1140/epjc/s10052-014-3168-9 %P 3168-31pp
