N2 - Measurements by the Belle Collaboration of the exclusive J/ψ + ηc and inclusive J/ψ + cc̄ + 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.
