| Abstract: A search for Kaluza-Klein (KK) gluon resonances, $ \mathrm{g_{KK}} $, decaying in cascade into two W bosons and a gluon via a scalar radion R, $ \mathrm{g_{KK} \rightarrow gR \rightarrow gWW} $, is presented. The final state with three large-radius jets, two of which contain the products of hadronically decaying W bosons is considered. The search is performed with $ \sqrt{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} $. Both the $ \mathrm{g_{KK}} $ and the R resonances are reconstructed. The ratio of their masses is used for event categorization, and the trijet mass distribution is used to extract a potential signal. Upper limits are set on the product of the $ \mathrm{g_{KK}} $ production cross section and branching fraction to $ \mathrm{gWW} $. Additionally, lower limits are set on the two resonance masses for an extended warped extra-dimensional model in which the quantum chromodynamics sector propagates into the extended bulk. This search is the first of its kind. | ||
