"Could Charm (\& $\tau$) Transitions be the `Poor Princesses' of Deeper Understanding of Fundamental Dynamics?" -- or -- "Finding Novel Forces?"

Abstract

We know that `our' Universe consists of `known' matter only $\sim$ 4.5\%: our understanding is incomplete seeing directly in neutrino oscillations (never mind about `other' Universes). Charm quarks had great impact on our understanding of known matter. QCD is the only local quantum field theory to describe strong forces. We can learn novel lessons about strong dynamics by measuring rates around the thresholds of $[\bar{Q}Q]$ states with $Q=b,c$. Furthermore they give us gateways for New Dynamics (ND), where we have to go from `accuracy' to `precision' eras. Finally we can connect with $\tau$ transitions and -- maybe -- with dark matter. Charm dynamics acts as a bridge between the worlds of light flavor hadrons with the heavy one, namely beauty hadrons. Finding {\em regional asymmetries} in many-body final states could be a `game changer'. There are several different `roads' to get closer to our goals: experiments act as gatekeepers like Super-tau-charm-factories, Super-beauty-factories and/or Super-$Z^0$-factories -- and deeper thinking about symmetries.
