dc.description.abstract | A search for narrow resonances that decay into t (t) over bar pairs has been performed using 130 pb(-1) of data in the lepton + jets channel collected by the DO detector in p (p) over bar collisions at roots=1.8 TeV. There is no significant deviation observed from the standard-model predictions at a top-quark mass of 175 GeV/c(2). We therefore present upper limits at the 95% confidence level on the product of the production cross section and branching fraction to t (t) over bar for narrow resonances as a function of the resonance mass M-X. These limits are used to exclude the existence of a leptophobic top-color particle with mass M-X<560 GeV/c(2), using a theoretical cross section for a width Gamma(X)=0.012M(X). | |
