Search for resonant tt̄ production in pp̄ collisions at s=1.96TeV

2008
We report on a search for narrow-width particles decayingto a top and antitop quark pair. The data set used in the analysis corresponds to an integrated luminosity of 680 pb -1 collected with the Collider Detectorat Fermilabin run II. We present 95% confidence level upper limits on the cross section times branching ratio. Assuming a specific top-color-assisted technicolor production model, the leptophobic Z' with width Γ z' = 0.012M z ,, we exclude the mass range M z' < 725 GeV/c 2 at the 95% confidence level.
