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...

In combination with a previous measurement restricted to leptonic final states with no associated jets, the fiducial cross section of WW production with zero or one jet is measured to be σ WW fid,≤1-jet = 511 ±9 (stat)±26 (syst)±10 (lumi)fb. The ratio of fiducial cross sections in final states with one and zero jets is determined to be 0.36 ±0.05.
