| Resumen |
We report a search for a narrow tt¯ resonance that decays into a lepton+jets final state based on an integrated luminosity of 5.3 fb−1 of proton-antiproton collisions at √s=1.96 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 tt¯. We exclude a leptophobic topcolor Z′ 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. |
