Excited State Contributions to the Heavy Baryon Fragmentation Functions in a Quark-Diquark Model
Abstract
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 b production rate and polarization at LEP energies are in agreement with experiment. The c and c functions are also obtained. The spin independent f1(z) is compared to data. The integrated values for production rates agree with the data.
