|Abstract: ||I illustrate the role of infrared renormalons in computing inclusive B-decay spectra.
I explain the relation between the leading ambiguity in the definition of Sudakov
form factor exp(N /M) and that of the pole mass, and show how these ambiguities
cancel out between the perturbative and non-perturbative components of
the b-quark distribution in the meson.|
