Search for Resonances Decaying to Three W Bosons in Proton-Proton Collisions at √s=13 TeV

A 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 ffiffiproton-proton collisions with the CMS detector at p s 1/4 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 extradimensional model. These searches are the first of their kind at the LHC.

Automated summary

A search for resonances decaying into a W boson and a radion is conducted using data analyzed from proton-proton collisions with the CMS detector at 13 TeV. The results find no excess over the background estimation, and limits are set on parameters of an extended warped extradimensional model. This is the first search of its kind at the LHC.
