Theory And Experiment

We comment on heavy quark fragmentation models motivated by QCD and study the influence of bound state and radiative corrections on heavy quark fragmentation emphasizing the comparison between the theoretical predictions and experimental data. It seems that meson constituents internal motion and initial state QCD gluon radiation may have a kinematical role in improving the agreement between theory and experiment. These effects are more striking in the case of charm fragmentation.
