Abstract

We have analyzed the available data on ppˉttˉp\bar{p}\,\rightarrow\, t\, \bar{t} followed by the decays (tbW+,tˉbˉWt\rightarrow bW^{+},\: \bar{t}\rightarrow \bar{b}W^{-}) which lead to e±μ2jetse^{\pm}\mu^{\mp}2 \mathrm{jets} or l±4jetsl^{\pm}4 \mathrm{jets} configurations, using a likelihood method we proposed earlier. The outcome is compared with the recent CDF analysis. In an appendix, we discuss the nature of the additional ``slow'' μ+\mu^{+} observed in one CDF dilepton event, concluding that it is most probably a ``tertiary lepton'' resulting from the decay sequence bc+hadronsb\rightarrow c +\mathrm{hadrons}, followed by csμ+νc\rightarrow s \mu^{+} \nu.
