The three-body decays a heavy Higgs [Formula: see text], [Formula: see text] and of a heavy top t → bW+ H are studied in the context of the Standard Model. The common feature of these decay channels is the relative big coupling constant of the Higgs particle to the top quark. Indeed within a certain range of the masses M H , mt we find that branching ratios of the order O(10-3) are possible for the decays [Formula: see text] and t → bW+ H. The decay with [Formula: see text] as a function of M H and mt is investigated below the 2mt threshold (Mtt < 2mt) and is found to have an interesting behaviour just near this threshold.
