Abstract

We calculate the α_s corrections to the form factors which parameterize the hadronic tensor relevant for inclusive semileptonic B → X τν_τ and Λ_b → X τν_τ decays. We apply our results to the double differential decay rates for the decays of B mesons and polarized Λ_b baryons to polarized τ leptons, presenting them in terms of one-dimensional integrals. Formulas appropriate for insertion into a Monte-Carlo simulation are presented.
