Abstract: We report on a search for narrow-width particles decaying to a top andantitop quark pair. The data set used in the analysis corresponds to anintegrated luminosity of 680 pb^{-1} collected with the Collider Detector atFermilab in Run II. We present 95% confidence level upper limits on the crosssection times branching ratio. Assuming a specific topcolor-assistedtechnicolor production model, the leptophobic Z- with width\Gamma {Z-}=0.012M {Z-}, we exclude the mass range M {Z-} < 725 GeV-c^2 at the95% confidence level.
