Inclusive Production of Four Charm Hadrons at B-Factories

Abstract

Measurements by the Belle Collaboration of the exclusive J/psi + eta_c and inclusive J/psi +cc-bar+X productions in e^+ e^- annihilation differ substantially from theoretical predictions based on the nonrelativistic QCD factorization approach. In order to test if such a discrepancy is originated from the large perturbative corrections to the hard-scattering amplitude, we study inclusive production of four charm hadrons in e^+e^- annihilation at B factories.
