Abstract

I discuss the heavy quark expansion for the inclusive widths of heavy-light hadrons, which predicts quite well the experimental ratios of Bq meson lifetimes. As for Λb, current determinations of O(mb-3) contribution to τ(Λb) do not allow to explain the small measured value of τ(Λb)/τ(Bd). As a final topic, I discuss the implications of the measurement of the Bc lifetime.
