Description

Measurements of W+jets and Z+jets cross sections (including the case where at least one jet contains a b-hadron) in proton-proton collisions with the ATLAS detector are reported. Cross sections, in both the electron and muon decay modes of the bosons, are presented as a function of jet multiplicity and of the transverse momentum of the leading and next-to-leading jets in the event. Measurements are also presented of the ratios of cross sections. The measured cross sections are compared to particle-level predictions based on higher-order perturbative QCD.
