  A new technique is discussed that can be applied to $\Lambda_b^0$ baryon
decays where decays with one missing particle can be discerned from background
and their branching fractions determined, along with other properties of the
decays. Applications include measurements of the CKM elements $|V_{ub}|$ and
$|V_{cb}|$, selected charmless decays, and detection of any exotic objects
coupling to $b\to s$ decays, such as the inflaton.
