Excited State Contributions to the Heavy Baryon Fragmentation Functions in a Quark-Diquark Model
A. Adamov, Gary R. Goldstein
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 Λb production rate and polarization at LEP energies are in agreement with experiment. The Λc and Ξc functions are also obtained. The spin independent f1(z) is compared to data. The integrated values for production rates agree with the data.
