dc.description.abstractThis paper presents a study of the production of WW or WZ boson pairs, with one W boson decaying to $e\nu $ or $\mu \nu $ and one W or Z boson decaying hadronically. The analysis uses $20.2~\text{ fb }^{-1}$ of $\sqrt{s} =8~\text {TeV}$ pp collision data, collected by the ATLAS detector at the Large Hadron Collider. Cross-sections for WW / WZ production are measured in high- $p_{\mathrm {T}}$ 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.
