The result is derived from a combined analysis of the searches performed by the ATLAS and CMS Collaborations with proton-proton collision data sets collected at the CERN Large Hadron Collider (LHC) from 2015 to 2018. These correspond to integrated luminosities of around 140 fb$^{-1}$ for each experiment, at a center-of-mass energy of 13 TeV. The measured signal yield is 2.2$\\pm$0.7 times the Standard Model prediction, and agrees with the theoretical expectation within 1.9 standard deviations.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.142406.v1/t1","@type":"Dataset","description":"The negative profile log-likelihood test statistic, where $\\Lambda$ represents the likelihood ratio, as a function of the signal strength $\\mu$...","name":"Profile likelihood scan"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins2666787?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/142406"}],"inLanguage":"en","name":"Evidence for the Higgs boson decay to a $Z$ boson and a photon at the LHC","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins2666787?version=1","version":1}
