TI  - A measurement of the ratio of the production cross sections for W and Z bosons in association with jets with the ATLAS detector
N2  - The ratio of the production cross sections for   W  and   Z  bosons in association with jets has been measured in proton?proton collisions at   s?=7TeV  with the ATLAS experiment at the Large Hadron Collider. The measurement is based on the entire 2011 dataset, corresponding to an integrated luminosity of   4.6fb?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.
