Abstract

We use 106 pb/sup -1/ of data collected with the Collider Detector at Fermilab to search for narrow-width, vector particles decaying to a top and an antitop quark. Model independent upper limits on the cross section for narrow, vector resonances decaying to tt are presented. At the 95% confidence level, we exclude the existence of a leptophobic Z' boson in a model of top-color-assisted technicolor with mass M/sub Z'/ lt 480 GeV/c/sup 2/ for natural width Gamma =0.012M/sub Z'/, and M/sub Z'/ lt 780 GeV/c/sup 2/ for Gamma =0.04M/sub Z'/.
