Search for heavy resonances decaying into tt¯ pairs
Abstract
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 pp¯ 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 Z' boson in a topcolor-assisted technicolor model with a mass MZ' < 725 GeV/c2, and our results can be used to constrain any other relevant theoretical model.
