Abstract

We apply analytic perturbation theory in next-to-next-to-leading order to inclusive semileptonic τ-decay and study the renormalization scheme dependence. We argue that the renormalization scheme ambiguity is considerably reduced in the analytic perturbation theory framework and we obtain a rather stable theoretical prediction.
