Abstract: We report a search for a narrow $t\overline{t}$ resonance that decays into a $\mathrm{\text{lepton}}+\mathrm{\text{jets}}$ final state based on an integrated luminosity of $5.3\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ of proton-antiproton collisions at $\sqrt{s}=1.96\text{ }\text{ }\mathrm{TeV}$ collected by the D0 Collaboration at the Fermilab Tevatron Collider. We set upper limits on the production cross section of such a resonance multiplied by its branching fraction to $t\overline{t}$. We exclude a leptophobic topcolor ${Z}^{\ensuremath{'}}$ at the 95% confidence level for masses below 835 GeV (940 GeV) if its width is 1.2% (3%) of its mass. We also exclude color octet vector bosons (colorons) with masses below 775 GeV.
