Method of Studying $\Lambda_b^0$ decays with one missing particle

Abstract

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.
