Description
Our community has focused on two-body final states in B & D decays. The SM produces at least the leading source of CP violation in B transitions; none has been established yet in charm decays. It is crucial to measure three- and four-body final states (FS) with accuracy and to compare with predictions based on refined theoretical tools. Correlations between different final states (FS) based on CPT invariance are often not obvious, how to apply them and where. We have to probe regional asymmetries and use refined parameterization of the CKM matrix. One uses (broken) U- & V-spin symmetries for spectroscopy. The situations with weak decays of hadrons are much more complex. The impact of strong re-scattering is large, and it connects U- & V-spin symmetries. Drawing diagrams often does not mean we understand the underlying dynamics. I give a few comments about probing the decays of beauty & charm baryons. I discuss the ‘strategies’ more than the ‘tactics’.
