Abstract: The production of a W boson decaying to ev or μv in association with a W or Z boson decaying to two jets is studied using 4.6 fb⁻¹ of proton-proton collision data at √s = 7 TeV recorded with the ATLAS detector at the LHC. The combined WW + WZ cross section is measured with a significance of 3.4σ and is found to be 68 ± 7 (stat.) ± 19 (syst.) pb, in agreement with the Standard Model expectation of 61.1 ± 2.2 pb. The distribution of the transverse momentum of the dijet system is used to set limits on anomalous contributions to the triple gauge coupling vertices and on parameters of an effective-field-theory model.
