Yetkin, Elif Aslı2022-10-172022-10-172022-07-080031-9007https://hdl.handle.net/11411/4577https://doi.org/10.1103/PhysRevLett.129.021802A search for resonances decaying into a W boson and a radion, where the radion decays into two W bosons, is presented. The data analyzed correspond to an integrated luminosity of 138 fb-1 recorded in proton-proton collisions with the CMS detector at s=13 TeV. One isolated charged lepton is required, together with missing transverse momentum and one or two massive large-radius jets, containing the decay products of either two or one W bosons, respectively. No excess over the background estimation is observed. The results are combined with those from a complementary channel with an all-hadronic final state, described in an accompanying paper. Limits are set on parameters of an extended warped extra-dimensional model. These searches are the first of their kind at the LHC. © 2022 CERN.eninfo:eu-repo/semantics/openAccessArticle2-s2.0-8513402362910.1103/PhysRevLett.129.02180235867460Q1WOS:000828087900020
