We report the results of a search for a heavy neutral gauge boson Z' decaying into the dielectron final state using data corresponding to an integrated luminosity of 5.4 fb-1 collected by the D0 experiment at the Fermilab Tevatron Collider. No significant excess above the standard model prediction is observed in the dielectron invariant-mass spectrum. We set 95% C.L. upper limits on \sigma (ppbar -> Z') X BR(Z' -> ee) depending on the dielectron invariant mass. These cross section limits are used to determine lower mass limits for Z' bosons in a variety of models with standard model couplings and variable strength.

Discussion (0). Continue with ORCID to comment.

  1. Search for a neutral gauge boson with nonuniversal fermion couplings in vector boson fusion processes in proton-proton collisions at $\sqrt{s}$ = 13 TeV

    hep-ex 2024-12 conditional novelty 6.0 of 10

    CMS finds no evidence for a VBF-produced Z' boson with nonuniversal fermion couplings and excludes masses up to 2.45 TeV (tau-tau) and 1.60 TeV (WW), assuming 50% branching fractions and maximal W coupling.

    hep-ph 2025-01 conditional novelty 5.0 of 10

    A 3-10 TeV muon collider could detect a heavy dark Z boson in photon-associated production, reaching kinetic-mixing strengths down to about 10^-3 near the kinematic limit by using resolution-optimized recoil-mass and ...
