We estimate the non-perturbative power-suppressed corrections to heavy flavour fragmentation and correlation functions in e + e − annihilation, using a model based on the analysis of one-loop Feynman graphs containing a massive gluon. This approach corresponds to the study of infrared renormalons in the large-n f limit of QCD, or to the assumption of an infrared-finite effective coupling at low scales. We find that the leading corrections to the heavy quark fragmentation function are of order… CONTINUE READING
