摘要：

In top-quark decays, there may be competition between decays mediated by real or virtual W bosons and decays into a charged Higgs boson. We evaluate the branching fractions to delineate the regions where standard top signals would be suppressed for two-Higgs-doublet models. We also show that both the standard semileptonic-decay signals tbW+bl and unconventional signatures such as tbH+b may be simultaneously suppressed with suitable parameter choices for any top-quark mass; in such circumstances the top quark would be very difficult to detect at hadron colliders. © 1990 The American Physical Society.
