This Letter presents the first study of WWjj, same-electric-charge diboson production in associationwith two jets, using 20.3 fb−1 of proton-proton collision data at ffiffiffis p ¼ 8 TeV recorded by the ATLASdetector at the Large Hadron Collider. Events with two reconstructed same-charge leptons (ee, eμ,and μμ) and two or more jets are analyzed. Production cross sections are measured in two fiducialregions, with different sensitivities to the electroweak and strong production mechanisms. First evidencefor WWjj production and electroweak-only WWjj production is observed with a significance of 4.5and 3.6 standard deviations, respectively. The measured production cross sections are in agreement withstandard model predictions. Limits at 95% confidence level are set on anomalous quartic gauge couplings.
