College Pk: Amer Physical Soc, v. 85, n. 5, p. 7, 2012.1550-7998http://hdl.handle.net/11449/24629We report a search for a narrow t (t) over bar resonance that decays into a lepton + jets final state based on an integrated luminosity of 5.3 fb(-1) of proton-antiproton collisions at root 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 t (t) over bar. 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.7engArtigo10.1103/PhysRevD.85.051101WOS:000301477700001Acesso abertoWOS000301477700001.pdf
