Abstract [en]

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 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. For the sequential standard model Z boson a lower mass limit of 1023 GeV is obtained.
