Abstract:

An analytical study was carried out to account for spin correlation effects in the production of tt̄ pairs in pp̄ collisions at √s=1.8 TeV. It was found that κ > -0.25 at the 68% confidence level.

Abstract:

Top quark production offers the unique opportunity to search for a charged Higgs boson (H^±), as the contribution from t→H⁺��→τ⁺νb can be large in extensions of the standard model. We use results from a search for top quark pair production by the Collider Detector at Fermilab (CDF) in the eτ+Slashed E signT+jets and μτ+Slashed E signT+jets signatures to set an upper limit on the branching ratio of ℬ(t→H⁺b) in 106 pb^-1 of data. The upper limit is in the range 0.5 to 0.6 at 95% C.L. for H⁺ masses in the range 60 to 160 GeV, assuming the branching ratio for H⁺→τν is 100%. The τ lepton is detected through its 1-prong and 3-prong hadronic decays. ©2000 The American Physical Society.
