    • Abstract

       

      Measurements of differential cross-sections of 𝑊 boson production in association with jets, and jets containing 𝑏 hadrons are presented. The measurements are based on 35 pb-1 of $pp$ collisions at $\sqrt{s} = 7$ TeV collected with the ATLAS detector at the LHC, using the electron and muon decay channels of the 𝑊 boson. The data are found to be compatible with next-to-leading order predictions. In addition, a study of the invariant mass distribution of jet pairs produced in association with a 𝑊 boson is presented, based on an integrated luminosity of 1.02 fb-1. The measured dijet mass shows no significant excess over the Standard Model expectation.
