We present a search for charged Higgs bosons in decays of pair-produced top quarks in pp̅ collisions at √s = 1.8TeV recorded by the D0 detector at the Fermilab Tevatron collider. With no evidence for signal, we exclude most regions of the ( MH±,tanβ) parameter space where the decay t→H+b has a branching fraction >0.36 and B(H±→τντ) is large.
