摘要：

We have searched for a heavy neutral gauge boson, Z', using the decay channel Z' --> ee. The data were collected with the DO detector at the Fermilab Tevatron during the 1992-1993 p(p) over bar collider run at root s = 1.8 TeV from an integrated luminosity of 15 +/- 1 pb(-1). Limits are set on the cross section times branching ratio for the process p(p) over bar --> Z' --> ee as a function of the Z' mass. We exclude the existence of a Z' of mass less than 490 GeV/c(2), assuming a Z' with the same coupling strengths to quarks and leptons as the standard model Z boson.
