Abstract: | © 2017 The Author(s) A search for heavy narrow resonances decaying into four-lepton final states has been performed using proton–proton collision data at s=8TeV collected by the CMS experiment, corresponding to an integrated luminosity of 19.7fb −1 . No excess of events over the standard model background expectation is observed. Upper limits for a benchmark model on the product of cross section and branching fraction for the production of these heavy narrow resonances are presented. The limit excludes leptophobic Z ′ bosons with masses below 2.5TeV within the benchmark model. This is the first result to constrain a leptophobic Z ′ resonance in the four-lepton channel. |
