The heavy-quarkonium decay {sup 3}S{sub 1}(Q{bar Q}){r arrow}Z+Higgs boson, a feasible process for Higgs-boson searches, is shown to be highly sensitive to the structure of the {ital HQ{bar Q}} vertex. A study of the angular distributions of the {ital Z} decay products can distinguish between the scalar or pseudoscalar form of this vertex and provide important information on the electroweak-symmetry-breaking mechanism.
