Abstract

We present a search for charged Higgs bosons in decays of pair-produced top quarks using 109.2 ± 5.8pb^-1 of data recorded from pp 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 [M_H+, tan β] 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 m_t = 175 GeV and σ(pp → tt) = 5.5 pb, for M_H+ = 60 GeV, we exclude tan β < 0.97 and tan β > 40.9.
