Measurement of production with the hadronically decaying boson reconstructed as one or two jets in collisions at with ATLAS, and constraints on anomalous gauge couplings.

This paper presents a study of the production of or boson pairs, with one boson decaying to or and one or boson decaying hadronically. The analysis uses of collision data, collected by the ATLAS detector at the Large Hadron Collider. Cross-sections for  /  production are measured in high- 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.
