This analysis is based on proton-proton collision data collected by the CMS experiment in 2015 corresponding to an integrated luminosity of 2.7 fb-1 delivered by the LHC operating at centre-of-mass energy of 13 TeV. The channel under study involves the production of a resonance X followed by the decay X → ZV → ℓ+ℓ+ jet, where V = W, Z and ℓ = μ,e. Upper limits at 95% confidence level are set for the production cross section of X decaying to a pair of Z bosons as function of the resonance mass. The results are interpreted in the context of the Randall-Sundrum warped extra dimensions model in the mass range between 550-2500 GeV. A localized excess at 650 GeV is observed in the data with global significance of 3.5 σ.engTrabalho apresentado em eventoAcesso aberto2-s2.0-85025825714
