Measurement of W + W - production in association with one jet in proton-proton collisions at √s = 8 TeV with the ATLAS detector

The production of Wboson pairs in association with one jet in pp collisions at √s = 8 TeV is studied using data corresponding to an integrated luminosity of 20.3 fb -1 collected by the ATLAS detector during 2012 at the CERN Large Hadron Collider. The cross section is measured in a fiducial phase-spa...
