Abstract
We have searched for heavy neutral gauge bosons () in p¯p collisions at √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±0.7 . We present a 95% confidence level upper limit on the production cross section times the branching ratio of decaying into dielectrons as a function of mass. Assuming standard model coupling strengths, we exclude a with a mass less than 505 GeV/. We also present lower mass limits for bosons from models and the alternative left-right model.
