Abstract
Predictions of the nonperturbative Quark Gluon Strings model,
based on the 1/N-expansion in QCD and string picture of interactions for
production of states containing heavy quarks are considered. Relations
between fragmentation functions for different states are used to predict
the fragmentation function of c-quark to J/ψ-mesons. The resulting
cross section for J/ψ-production in e+e--annihilation is in a
good agreement with recent Belle result. It is argued that associated production
of states with open charm should give a substantial contribution to
production of these states in hadronic interactions at very high energies.
