We have searched for heavy neutral gauge bosons ([ital Z][sup [prime]]) in [ital [bar p]p] collisions at [radical][ital s]=1.8 TeV. The data were obtained using the CDF detector during the 1992--1993 run corresponding to an integrated luminosity of 19.7[plus minus]0.7 pb[sup [minus]1]. We present a 95% confidence level upper limit on the production cross section times the branching ratio of [ital Z][sup [prime]] decaying into dielectrons as a function of [ital Z][sup [prime]] mass. Assuming standard model coupling strengths, we exclude a [ital Z][sup [prime]] with a mass less than 505 GeV/[ital c][sup 2]. We also present lower mass limits for [ital Z][sup [prime]] bosons from E[sub 6] models and the alternative left-right model.
