Threshold production of charmed and B mesons in e+e- annihilation
  A simple extension of the QCD inspired potential model which includes dynamical quarks first proposed by Eichten et al. is remarkably successful in accounting both for the observed narrow state heavy quarkonium spectroscopy and experimental data on threshold production of charmed and B mesons in e+e- annihilation. In addition to this model, a variant of it can also account for the data. The cross section data are mainly inclusive cross section measurements. The two models give distinguishably different predictions for the energy dependence of production cross sections for individual channels, and measurment of the energy dependence of production cross sections for individual channels may distinguish between these models.
