Fragmentation production of $\Omega_{ccc}$ baryons at LHC energies

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 Omega /sub ccc/ baryon are calculated in the leading order of perturbative QCD. The cross section for Omega /sub ccc/ production in high-energy hadron interactions is estimated. It is assumed that Omega /sub ccc/ baryons are formed via the fragmentation of a c quark or a vector (cc) diquark produced in the partonic subprocesses gg to cc, qq to cc, gg to (cc)+c+c, and qq to (cc)+c+c.
