Search for the charged Higgs boson in the decays of top quark pairs in the <em>eτ</em> and <em>μτ</em> channels at s√=1.8 TeV

In summary, we have performed a search for a charged Higgs boson in top quark decays using measurements of the top pair production cross section in four different final states, and

We observe no significant excess over the expected background and thus set 95% confidence level upper limits on the Higgs boson production cross section for several Higgs boson

The measured distribution (points) in the fitted top-quark mass in events with a Z and four jets with at least one b -tagged jet, compared to the SM expectations and an FCNC

In the CDF II data sample of 2 : 2 fb 1 , we find no evidence of charged Higgs bosons in the dijet mass spectrum of the top quark decays. This analysis also yields conservative

After basic event selection, the total expected signal event yield in the current data set is 5:1 0:5 ( 3:5 0:4 ) single (double)-tag events for a Higgs boson with a mass of 115

To determine the observed (expected) exclusion contour in the stop-sneutrino mass plane, we set the number of events equal to the number of events in the data (total
