Search for leptophobic Z‧ bosons decaying into four-lepton final states in proton-proton collisions at √{ s} = 8TeV

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.
