Abstract

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