Abstract: A search for a heavy scalar resonance decaying to two Z bosons and subsequently to four leptons is presented, where the leptons can be electrons or muons. The results are based on the proton-proton collision data collected by the CMS experiment at the LHC at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 138 fb$^{-1}$. The searches are performed in a model independent way over a range of resonance mass from 130 GeV to 3 TeV, considering both narrow and wide width scenarios, and assuming that the resonance is produced via gluon fusion or vector boson fusion. For the wide width scenarios, the interference between the signal, the standard model Higgs production, and the continuum background are taken into account. No significant excess with respect to the standard model predictions is observed in the examined phase space, and upper limits at 95% confidence level on the production cross section of the resonance multiplied by the branching ratio of decaying to two Z bosons are computed.
