Using the electroweak theory of Weinberg and Salam in conjunction with the Bethe-Salpeter formalism, the authors calculate the contribution of the Z0, both the exchange and annihilation diagrams, to the hyperfine structure of toponium. As a function of the Higgs mass, they also calculate the contribution of a single Higgs boson to the hyperfine structure. Furthermore, they examine both the electromagnetic and strong contribution to the hyperfine structure.
