Abstract

The W boson angular distribution in events with high transverse momentum jets is measured using data collected by the ATLAS experiment from proton–proton collisions at a centre-of-mass energy View the MathML sources=8 TeV at the Large Hadron Collider, corresponding to an integrated luminosity of 20.3 fb−120.3 fb−1. The focus is on the contributions to W+jetsW+jets processes from real W emission, which is achieved by studying events where a muon is observed close to a high transverse momentum jet. At small angular separations, these contributions are expected to be large. Various theoretical models of this process are compared to the data in terms of the absolute cross-section and the angular distributions of the muon from the leptonic W decay.
