Search for a heavy neutral gauge boson in the dielectron channel with 5.4 fb-1 of ppbar collisions at root s=1.96 TeV
Original language description
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 sigma(p (p) over bar -> Z´) x BR(Z´ -> ee) depending on the dielectron invariant mass. These cross section limits are used to determine lowermass limits for bosons in a variety of models. For the sequential standard model boson a lower mass limit of 1023 GeV is obtained.
