A search for Kaluza-Klein excited vector boson resonances, W KK , decaying in cascade to three W bosons via a scalar radion R, W KK → WR → WWW, in a final state containing two or three massive jets is presented. The search is performed with √ s = 13 TeV proton-proton collision data collected by the CMS experiment at the CERN LHC during 2016-2018, corresponding to an integrated luminosity of 138 fb −1 . Two final states are simultaneously probed, one where the two W bosons produced by the R

The observed data are in agreement with the standard model expectations. Limits are set on the product of the W KK resonance cross section and branching fraction to three W bosons in an extended warped extradimensional model and are the first of their kind at the LHC.
