Search for charged Higgs bosons in decays of top quark pairs

Abstract:

We present a search for charged Higgs bosons in decays of pair-produced top quarks using 109.2 ± 5.8 pb-1 of data recorded from pp̄ collisions at √s = 1.8 TeV by the D0 detector during 1992-1996 at the Fermilab Tevatron. No evidence is found for charged Higgs production, and most parts of the [MH+, tanβ] parameter space where the decay t → H+b has a branching fraction close to or larger than that for t → W+b are excluded at 95% confidence level. Assuming mt = 175 GeV and σ(pp̄ → tt̄) = 5.5 pb...
