Abstract
We report on the first direct search for charged Higgs bosons decaying into cs̅ in tt̅ events produced by pp̅ collisions at √s=1.96 TeV. The search uses a data sample corresponding to an integrated luminosity of 2.2 fb[superscript -1] collected by the CDF II detector at Fermilab and looks for a resonance in the invariant mass distribution of two jets in the lepton+jets sample of tt̅ candidates. We observe no evidence of charged Higgs bosons in top quark decays. Hence, 95% upper limits on the top quark decay branching ratio are placed at B(t→H[superscript +]b)< 0.1 to 0.3 for charged Higgs boson masses of 60 to 150 GeV/c[superscript 2] assuming B(H[superscript +]→cs̅ )=1.0. The upper limits on B(t→H[superscript +]b) are also used as model-independent limits on the decay branching ratio of top quarks to generic scalar charged bosons beyond the standard model.
