- Abstract
- This Letter presents the first study of W W jj, same-electric-charge diboson production in association with two jets, using 20.3 fb−1 of proton-proton collision data at ffiffiffi s p ¼ 8 TeV recorded by the ATLAS detector at the Large Hadron Collider. Events with two reconstructed same-charge leptons (e e , e μ , and μ μ ) and two or more jets are analyzed. Production cross sections are measured in two fiducial regions, with different sensitivities to the electroweak and strong production mechanisms. First evidence for W W jj production and electroweak-only W W jj production is observed with a significance of 4.5 and 3.6 standard deviations, respectively. The measured production cross sections are in agreement with standard model predictions. Limits at 95% confidence level are set on anomalous quartic gauge couplings.
