Superheavy toponium. psi. sub t (1--) bound via Higgs-Boson exchange

In this paper a possible existence of superheavy toponium {psi}{sub t}(1{sup {minus}{minus}}) bound via Higgs-boson exchange is discussed in the framework of two Higgs-doublet model. It is pointed out that the Drell ratio distribution is a very good measure of Higgs-boson exchange because of its special decay property of the {psi}{sub t}(1{sup {minus}{minus}}).
