Search for Heavy Resonances Decaying into $$t\bar{t}$$ Pairs
- Univ. of Florida, Gainesville, FL (United States)
We performed a search for narrow-width vector particles decaying into top-antitop pairs using 680 pb-1 of data collected by the CDF experiment during 2002-2005 Run 2 of the Tevatron. The center of mass energy of the $$p\bar{p}$$ collisions was 1.96 TeV . Model independent upper limits on the production cross-section times branching ratio are derived, at 95% confidence level. We exclude the existence of a leptophobic Zt boson in a topcolor-assisted technicolor model with a mass MZ' < 725GeV/c2, and our results can be used to constrain any other relevant theoretical model.
