The result is derived from a combined analysis of the searches performed by the ATLAS and CMS Collaborations with proton-proton collision datasets collected at the CERN Large Hadron Collider (LHC) from 2015 to 2018. These correspond to integrated luminosities of around Formula Presented for each experiment, at a center-of-mass energy of 13 TeV. The measured signal yield is Formula Presented times the standard model prediction, and agrees with the theoretical expectation within 1.9 standard deviations. © 2024 CERN, for the ATLAS and CMSs Collaboration.eninfo:eu-repo/semantics/openAccessBosonsLarge DatasetsStatisticsA-CenterCombined AnalysisHiggs Boson DecayIntegrated LuminosityLarge Hadron ColliderLarge-Hadron CollidersProton Proton CollisionsStandard DeviationStatistical SignificanceZ BosonsPhotonsArticleBosonControlled StudyHumanMajor Clinical StudyPhotonArticle1322382776072-s2.0-8518224684910.1103/PhysRevLett.132.021803N/A
