Abstract
We search for resonant production of tt̅ pairs in 4.8  fb[superscript -1] integrated luminosity of pp̅ collision data at √s=1.96  TeV in the lepton+jets decay channel, where one top quark decays leptonically and the other hadronically. A matrix-element reconstruction technique is used; for each event a probability density function of the tt̅ candidate invariant mass is sampled. These probability density functions are used to construct a likelihood function, whereby the cross section for resonant tt̅ production is estimated, given a hypothetical resonance mass and width. The data indicate no evidence of resonant production of tt̅ pairs. A benchmark model of leptophobic Z′→tt̅ is excluded with m[subscript Z]′<900  GeV/c[superscript 2] at 95% confidence level.
