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

Understand

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 $Q = b, c$.
