Abstract

This paper presents a study of the production of <i>WW</i> or <i>WZ</i> boson pairs, with one <i>W</i> boson decaying to e ν or μ ν and one <i>W</i> or <i>Z</i> boson decaying hadronically. The analysis uses 20.2 fb - 1 of s = 8 TeV <i>pp</i> collision data, collected by the ATLAS detector at the Large Hadron Collider. Cross-sections for <i>WW</i> / <i>WZ</i> production are measured in high- p T fiducial regions defined close to the experimental event selection. The cross-section is measured for the case where the hadronically decaying boson is reconstructed as two resolved jets, and the case where it is reconstructed as a single jet. The transverse momentum distribution of the hadronically decaying boson is used to search for new physics. Observations are consistent with the Standard Model predictions, and 95% confidence intervals are calculated for parameters describing anomalous triple gauge-boson couplings.
