Abstract Within the nonrelativistic quark-diquark model for heavy baryons, the fragmentation functions for the transitions of a c-quark and a doubly charmed vector diquark into an Ωccc baryon are calculated in the leading order of perturbative QCD. The cross section for Ω ccc production in high-energy hadron interactions is estimated. It is assumed that Ωccc baryons are formed via the fragmentation of a c quark or a vector (cc) diquark produced in the partonic subprocesses gg → c $$\bar c$$ , q $$\bar q$$ → c $$\bar c$$ , gg → (cc)+ $$\bar c$$ + $$\bar c$$ , and q $$\bar q$$ → (cc)+ $$\bar c$$ + $$\bar c$$ .
