Bridge between Hadrodynamics & HEP: Regional CP Violation in Beauty & Charm Decays

There is a long way from `accuracy' to `precision' about {\bf CP} asymmetries in the decays of beauty \& charm hadrons. (a) We have to apply consistent parametrization of the CKM matrix. (b) Probing many-body final states (FS) is {\em not} a back-up for understanding the underlying forces; to be realistic we can hardly go beyond four-body FS. (c) Broken U-spin symmetry is a good tools to describe spectroscopy of hadrons.However the landscape is very different for weak transitions; the connection of U- \& V-spin symmetries are important. We have to understand the differences between Penguin {\em operators} vs. Penguin {\em diagrams}. (d) Collaborations of experimenters \& theorists are crucial with {\em judgment}. There is a `hot' news from the conference ICHEP2016: LHCb data show evidence of {\bf CP} asymmetries in the {\bf T}-odd moment from $\Lambda_b^0 \to p \pi^-\pi^+\pi^-$. LHCb will follow this `road' with $\Lambda_b^0 \to p \pi^-K^+K^-$, $\Lambda_b^0 \to p K^- \pi^+\pi^-$ \& $\Lambda_b^0 \to p K^-K^+K^-$ in run-1. With much more data it is crucial to probe its features in {\em regional} asymmetries. \\ A quote from Marinus, who was a $\sim$ 468 AD student of Proklos, a well-known Neoplatonic philosopher: "Only {\em being} good is one thing -- but good {\em doing} it is the other one!"
