The cross-section is found to be $2.01 \\pm 0.30 (stat.) \\pm 0.16 (syst.) fb$. The corresponding Standard Model predicted cross-section calculated at next-to-leading order in perturbative quantum chromodynamics and at leading order in the electroweak coupling constant is $1.50 \\pm 0.06 fb$. The observed significance of the $WZ\\gamma$ signal is $6.3\\sigma$, compared with an expected significance of $5.0\\sigma$.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.144507.v1/t1","@type":"Dataset","description":"Events in bins of the photon $p_{\\mathrm{T}}^{\\gamma}$ in the SR.","name":"Table 1"},{"@id":"https://doi.org/10.17182/hepdata.144507.v1/t2","@type":"Dataset","description":"Events in bins of the $p_{\\mathrm{T}}^{\\ell_{1}}$ in the SR.","name":"Table 2"},{"@id":"https://doi.org/10.17182/hepdata.144507.v1/t3","@type":"Dataset","description":"Events in bins of the $m(\\ell\\ell)$ in the SR.","name":"Table 3"},{"@id":"https://doi.org/10.17182/hepdata.144507.v1/t4","@type":"Dataset","description":"Events in bins of the $E_{miss}^T$ in the SR.","name":"Table 4"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins2663046?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/144507"}],"inLanguage":"en","name":"Observation of $WZ\\gamma$ production in $pp$ 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/ins2663046?version=1","version":1}
