Title: Heavy mass expansion in [Lambda][sub [ital b]][r arrow][Lambda][sub [ital c]] decays

We point out that in the decays of the [Lambda][sub [ital b]] to [Lambda][sub [ital c]] one can find predictions which, in the framework of the 1/[ital m][sub [ital c]] expansion, do not receive corrections in any order of 1/[ital m][sub [ital c]]. We discuss QCD corrections to these predictions and examine some of the consequences for nonleptonic decays.
