Abstract

The hadronization effects induced by different colour connections of ccˉqqˉc\bar{c}q\bar{q} system in e+ee^+e^- annihilation are investigated by a toy model where diquark fragmentation is employed based on Pythia. It is found that the correlations between the charm baryons and charm antibaryons produced via diquark pair fragmentation are much stronger, and their momentum spectra are harder than those from the standard colour connection in Pythia.
