Abstract:
We describe a model to include non-perturbative corrections to heavy-quark fragmentation, based on next-to-next-to-leading logarithmic threshold resummation and on an effective QCD coupling not containing the Landau pole. We present a phenomenological comparison between the predictions of the model and experimental data from B and D meson fragmentation in e(+)e(-) annihilation.
