A search for Kaluza-Klein excited vector boson resonances, WKK , decaying in cascade to three W bosons via a scalar radion R, WKK → WR → WWW, in a final state containing two or three massive jets is presented. The search is performed with ffiffiffi s p ¼ 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 decay are reconstructed as separate, large-radius, massive jets, and one where they are merged into a single large- radius jet. The observed data are in agreement with the standard model expectations. Limits are set on the product of the WKK resonance cross section and branching fraction to three W bosons in an extended warped extra-dimensional model and are the first of their kind at the LHC.

Abstract

A search for Kaluza-Klein excited vector boson resonances, WKK , decaying in cascade to three W bosons via a scalar radion R, WKK → WR → WWW, in a final state containing two or three massive jets is presented. The search is performed with ffiffiffi s p ¼ 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 decay are reconstructed as separate, large-radius, massive jets, and one where they are merged into a single large- radius jet. The observed data are in agreement with the standard model expectations. Limits are set on the product of the WKK resonance cross section and branching fraction to three W bosons in an extended warped extra-dimensional model and are the first of their kind at the LHC.
