EnglishA search for heavy narrow resonances decaying into four-lepton final states has been performed using proton–proton collision data at collected by the CMS experiment, corresponding to an integrated luminosity of 19.7. 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 bosons with masses below 2.5 within the benchmark model. This is the first result to constrain a leptophobic resonance in the four-lepton channel.

| Abstract: | A search for heavy narrow resonances decaying into four-lepton final states has been performed using proton–proton collision data at collected by the CMS experiment, corresponding to an integrated luminosity of 19.7. 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 bosons with masses below 2.5 within the benchmark model. This is the first result to constrain a leptophobic resonance in the four-lepton channel. |
