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 root s = 8 TeV at the Large Hadron Collider, corresponding to an integrated luminosity of 20.3 fb(-1). The focus is on the contributions to W + 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. (C) 2016 The Author.

Cell & Developmental Biology contains resources in biochemistry, molecular biology, biophysics, physiology, and pharmacology that have a specific emphasis on cellular function in eukaryotic systems. Topics of particular importance include receptor biology and signal transduction, regulation of gene expression at the cellular level, developmental genetics, developmental biology and morphogenesis, and cell-environment interactions. Resources concentrated on molecular biochemistry and molecular regulation of gene expression, as well as microscopic or histological analysis of cell or tissue samples are excluded.
