Excited state contributions to the heavy baryon fragmentation functions in a quark-diquark model
Journal Article

· Physical Review D
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 explicitly included. The resulting {Lambda}{sub b} production rate and polarization at CERN LEP energies are in agreement with experiment. The {Lambda}{sub c} and {Xi}{sub c} functions are also obtained. The spin independent f{sub 1}(z) is compared to data. The integrated values for production rates agree with the data.
