Abstract:
A search for a heavy resonance decaying to ZγZ\gamma, with the Z boson further decaying to pairs of electrons or muons is presented. The search makes use of 13 TeV proton-proton collision data collected by the CMS experiment at the LHC, corresponding to an integrated luminosity of 2.7 fb12.7~\mathrm{fb}^{-1}. The analysis extracts the background directly from data, through an unbinned likelihood fit. No signifcant excess over the background-only hypothesis is observed, therefore limits at 95%95\% confidence level are set on the production cross section of particles with a mass between 350 GeV350~\mathrm{GeV} and 2 TeV2~\mathrm{TeV}, with two different assumptions on the resonance width.
