This paper presents a study of the production of WW or WZ boson pairs, with one W boson decaying to e? or µ? and one W or Z boson decaying hadronically. The analysis uses 20.2fb-1 of s=8TeVpp collision data, collected by the ATLAS detector at the Large Hadron Collider. Cross-sections for WW / WZ 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. © 2017, CERN for the benefit of the ATLAS collaboration.

Abstract
This paper presents a study of the production of WW or WZ boson pairs, with one W boson decaying to e? or µ? and one W or Z boson decaying hadronically. The analysis uses 20.2fb-1 of s=8TeVpp collision data, collected by the ATLAS detector at the Large Hadron Collider. Cross-sections for WW / WZ 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. © 2017, CERN for the benefit of the ATLAS collaboration.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
