摘要：

We evaluate the single-lepton spectra expected from the decays of b̄b and t̄t quarks in e+e- annihilation. The b → u and b → c transitions yield qualitatively different lepton-momentum distributions for b̄b production especially near threshold, and hence the ratio of coupling strengths can be deduced directly from experiment. Similar lepton spectral differences resulting from t̄t production can be used to determine the relative strength of t → s and t → b couplings. © 1979.
