Özet
This paper presents a study of the production of W W or W Z boson pairs, with one W boson decaying to e? or ?? and one W or Z boson decaying hadronically. The analysis uses 20.2 fb?1 of ?s = 8 TeV pp collision data, collected by the ATLAS detector at the Large Hadron Collider. Crosssections for W W/W Z production are measured in high-pT 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.
