  • A search for a heavy resonance (Z ′ → t̄t) in the t̄t invariant mass spectrum has been conducted in 682 pb−1 of CDF Run II data. For b-tagged t̄t candidates in the lepton+jets decay channel, we use the standard χ based mass-fit algorithm to reconstruct the Mtt̄ spectrum. Expected spectra from Standard Model top, non-top Standard Model backgrounds, and a candidate resonance of Z ′ → t̄t are modeled with Monte Carlo. A binned likelihood fit to the three components is performed for Z ′ masses from… CONTINUE READING
