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

Abstract

In the framework of quark-hadron duality, the cross section values of charmonium and doubly charmed baryon production in $e^{+}{e}^{-}$-annihilations have been estimated at interaction energy $\sqrt{s}=10.6$ GeV. It has been shown that the approach under discussion allows to resolve some contradictions between the experimental data and pQCD predictions.
