Abstract

We use current-current interaction to calculate the fragmentation functions to describe the production of spin-1/2, spin-1/2^\ensuremath', and spin-3/2 baryons with massive constituents in a relativistic quark-diquark model. Our results are in their analytic forms and are applicable for singly, doubly, and triply heavy baryons. We discuss the production of \ensuremathΩ_bbc, \ensuremathΩ_bcc, and \ensuremathΩ_ccc baryons in some detail. The results are satisfactorily compared with those obtained for triply heavy baryons calculated in a perturbative regime within reasonable values of the parameters involved.
