Search for Narrow t-tbar Resonances in ppbar Collisions at \root{s} = 1.8 TeV

Abstract

A search for narrow resonances that decay into t-tbar pairs has been performed using 130 pb^{-1} of data in the lepton+jets channel collected in p-pbar collisions at \sqrt{s} = 1.8 TeV. There is no significant deviation observed from the standard model, and upper limits at the 95 % confidence level on the product of the production cross section and branching fraction to t-tbar are presented for narrow resonances as a function of the resonance mass M_X. These limits are used to exclude the existence of a leptophobic topcolor particle with mass M_X < 560 GeV/c^2 and width Γ_X = 0.012 M_X.
