Journal of high energy physics № 1. P. 049 (1-41)Abstract: The production of a W boson decaying to e or μ 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 3.4 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.
