Quark-hadron duality and production of charmonia and doubly charmed baryons in e+e- anninhilation

The cross sections for the production of charmonia and doubly charmed baryons in e(+)e(-) annihilation at an interaction energy of root s = 10.6 GeV are predicted under the assumption of quark-hadron duality. The method used is shown to remove some contradictions between experimental data and perturbative QCD.
