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 = 8 TeV collected by the CMS experiment, corresponding to an integrated luminosity of 19.7 fb−1. No excess of events over the standard model background expectatio...

| description | A search for heavy narrow resonances decaying into four-lepton final states has been performed using
proton–proton collision data at √s = 8 TeV collected by the CMS experiment, corresponding to an
integrated luminosity of 19.7 fb−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 2.5 TeV within the benchmark model. This is the first result to constrain a
leptophobic Z resonance in the four-lepton channel |
