The analysis is sensitive to the scattering of $W$ bosons, which is of particular interest in the ATLAS physics programme as it can be used to probe the electroweak symmetry breaking mechanism of the Standard Model. This signal is observed with a significance of 7.1 standard deviations above the background expectation, while 6.2 standard deviations were expected. The measured cross-section is determined in a signal-enriched fiducial volume and is found to be $2.7\\pm0.5\\,\\mathrm{fb}$, which is consistent with the theoretical prediction of $2.20^{+0.14}_{-0.13}\\,\\mathrm{fb}$.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.153883.v1/t1","@type":"Dataset","description":"Measurement of the signal strength $\\mu=\\mu(EWK\\;W^+ W^- jj)$ from the likelihood fit described in Section 8 together with the normalisations...","name":"Measured and predicted signal and background strength"},{"@id":"https://doi.org/10.17182/hepdata.153883.v1/t2","@type":"Dataset","description":"Measurement of the measured and predicted signal cross-section.","name":"Measured and predicted signal cross-section"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins2766986?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/153883"}],"inLanguage":"en","name":"Observation of electroweak production of $W^+W^-$ in association with jets in proton-proton collisions at $\\sqrt{s}=13$ TeV with the ATLAS Detector","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins2766986?version=1","version":1}
