Search for resonances decaying to three W bosons in the hadronic final state at $\sqrt{s} = $ 13 TeV

Abstract: A search for heavy resonances X decaying in cascade to three W bosons via a scalar radion R, X $\to$ WR $\to$ WWW, with two or three massive, Lorentz-boosted jets is presented. The search is performed with proton-proton collision data recorded at $\sqrt{s} = $ 13 TeV collected by the CMS experiment during 2016-2018, corresponding to an integrated luminosity of 137 fb$^{-1}$. Two final states are simultaneously probed, one where the two W bosons produced by the R decay are reconstructed as separate jets, and one where they are reconstructed as a single merged jet. The data observed are in agreement with the standard model expectations. Results are combined with a complementary and orthogonal search in the single-lepton channel to set the most stringent limits to date on the production cross section of an extended warped extra-dimensional model.
