Abstract

At high energy hadron collider, the dominant production mechanism for heavy baryons is actually the fragmentation. We analytically have computed the effect of spin orientation of heavy quarks Q in the production heavy triply baryons through fragmentation in leading order perturbative QCD. Our analytical results have been presented for the spin dependent fragmentation Functions for fragmentation processes b→𝛺bbc and c→𝛺ccb. The production of intermediate spin 1/2 and 3/2 excited states is explicity included. The global fragmentation probabilities fall off within the range of 10−5–10−6. After evaluation of fragmentation functions by Altareli-Parisi equation, cross section production of all case 𝛺bbc and 𝛺ccb at the LHC. (\( \sqrt{S}=14\mathrm{TeV} \)) have been calculated. The total cross section production falls off within the range 21–166 pb.
