We present a model to include non-perturbative corrections to heavy-quark fragmentation. The model is based on next-to-next-to-leading logarithmic perturbative threshold resummation and on an analytic QCD coupling not containing the Landau pole. We compare the predictions of the model against the experimental data from B and D meson fragmentation in e+e- Annihilation. Our model gives a good description of the experimental data without introducing any free non-perturbative parameter.

Abstract
We present a model to include non-perturbative corrections to heavy-quark fragmentation. The model is based on next-to-next-to-leading logarithmic perturbative threshold resummation and on an analytic QCD coupling not containing the Landau pole. We compare the predictions of the model against the experimental data from B and D meson fragmentation in e+e- Annihilation. Our model gives a good description of the experimental data without introducing any free non-perturbative parameter.
