| Abstract: An observation of the combined production of three massive vector bosons (VVV with V = W, Z) in proton-proton collisions at a center-of-mass energy of 13 TeV is reported. The analysis is based on a data sample recorded by the CMS experiment at the CERN LHC corresponding to a total integrated luminosity of 137 fb$^{-1}$. The searches for individual WWW, WWZ, WZZ, and ZZZ production processes are performed in final states with three, four, five, and six leptons (electrons or muons), or with two same-charge leptons plus one or two jets. The observed (expected) significance of the combined VVV production signal is 5.7 (5.9) standard deviations (sd) and the corresponding measured signal strength is 1.02$^{+0.26}_{-0.23}$. The significances of the individual WWW and WWZ channels are 3.3 and 3.4 sd, respectively. The measured production cross sections for the individual triboson final states are also reported. | ||
