title = "Evidence of ZZγ Production and Observation of 4lγ in Proton-Proton Collisions at s=13 TeV",
abstract = "Why this matters The key point is that CMS is reporting evidence for \textbackslash{}(ZZ\textbackslash{}gamma\textbackslash{}) production for the first time in CMS. The 3.7σ result is conventionally described as evidence, rather than a 5σ observation. The separate inclusive \textbackslash{}(4\textbackslash{}ell\textbackslash{}gamma\textbackslash{}) analysis reaches 5.0σ, but that is a broader final state that includes final-state radiation and should not be interpreted as a 5σ observation of the specifically defined \textbackslash{}(ZZ\textbackslash{}gamma\textbackslash{}) production process. In one sentence: CMS has found statistically significant evidence for producing two \textbackslash{}(Z\textbackslash{}) bosons and a photon in proton{\textendash}proton collisions, with a measured rate broadly consistent with Standard Model expectations.",
