Abstract
In the context of the inclusive decay, we analyze various forms of perturbative expansions which have appeared as modifications of the original perturbative series. We argue that analytic perturbation theory, which combines renormalization-group invariance and analyticity, has significant merits favoring its use to describe the perturbative component of decay.
