Excited State Contributions to the Heavy Baryon Fragmentation Functions in a Quark-Diquark Model
Spin dependent fragmentation functions for heavy flavor quarks to fragment into heavy baryons are calculated in a quark-diquark model. The production of intermediate spin 1/2 and 3/2 excited states is explicity included. The resulting $\Lambda_b$ production rate and polarization at LEP energies are...
