The minimal prescription procedure is applied to tame the Landau pole singularities of resummed formulae for heavy quark decays. Effects of the final quark mass are taken into account. Explicit expressions are obtained for the t -> b and b -> c transitions for both the frozen coupling approximation and in the QCD running coupling case. RI Ricciardi, Giulia/H-3649-2011

Abstract
The minimal prescription procedure is applied to tame the Landau pole singularities of resummed formulae for heavy quark decays. Effects of the final quark mass are taken into account. Explicit expressions are obtained for the t -> b and b -> c transitions for both the frozen coupling approximation and in the QCD running coupling case. RI Ricciardi, Giulia/H-3649-2011
