Abstract:

 
 We present a search for charged Higgs bosons in decays of
 pair-produced top quarks in pbarp collisions at sqrt{s} = 1.8
 TeV. Using 62.2 pb^-1 of data recorded by the DZero detector at the
 Fermilab Tevatron collider, we find no evidence for Higgs signal in
 the tau-decay channel, and exclude at 95% confidence for most regions
 of the (m_H, tan(beta)) parameter space where the decay t->Hb has a
 branching fraction greater than 0.36 and B(H^+/- -> tau nu_tau) is
 large.
